SELECTION OF RESOLUTION MODE
The PD8882 has function of two readout modes, High Resolution Mode and Low Resolution Mode. These two modes can be selected by SEL switch.
Read Mode High Resolution Mode Low Resolution Mode 2400 dpi (Max.) 1200 dpi (Max.) (odd line readout mode) Description High level Low level
SEL
(1) High Resolution Mode In this mode, both signals in even lines and odd lines can be read out. This mode enables 2400 dpi (Max.) resolution with A4 size (210 x 297 mm, shorter side). Please refer to TIMING CHART 1-1, 1-2 and 2-1. (2) Low Resolution Mode In this mode, only signal in odd photocell arrays can be read out. This mode enables 1200 dpi (Max.) resolution with A4 size. To use intermittent reset drive enable signal charges of adjacent pixels in odd line to add at the charge to voltage conversion area. Then it can achieve low resolution with A4 size such as 600, 300 or 150 dpi. Please refer to TIMING CHART 1-3 to 1-8, 2-2 to 2-4.

DEFINITIONS OF CHARACTERISTIC ITEMS
1. Saturation voltage : Vsat Output signal voltage at which the response linearity is lost. 2. Saturation exposure : SE Product of intensity of illumination (lx) and storage time (s) when saturation of output voltage occurs. 3. Photo response non-uniformity : PRNU The output signal non-uniformity of all the valid pixels when the photosensitive surface is applied with the light of uniform illumination. This is calculated by the following formula.
PRNU (%) =

12. Random noise (CDS) : CDS Random noise CDS is defined as the standard deviation of a valid pixel output signal with 100 times (=100 lines) data sampling at dark (light shielding). CDS is calculated by the following procedure. 1. One valid photocell in one reading is fixed as measurement point. 2. The output level is measured during the reset feed-through period which is averaged over 100 ns to get "VDi". 3. The output level is measured during the video output time averaged over 100 ns to get "VOi". 4. The correlated double sampling output is defined by the following formula. VCDSi = VDi - VOi 5. Repeat the above procedure (1 to 4) for 100 times (= 100 lines). 6. Calculate the standard deviation CDS using the following formula equation.

RECOMMENDED SOLDERING CONDITIONS
When soldering this product, it is highly recommended to observe the conditions as shown below. If other soldering processes are used, or if the soldering is performed under different conditions, please make sure to consult with our sales offices. For technical information, see the following website. Semiconductor Device Mount Manual (http://www.necel.com/pkg/en/mount/index.html) Type of Through-hole Device
PD8882CY-A : CCD linear image sensor 22-pin plastic DIP (10.16 mm (400))
Process Partial heating method Conditions Pin temperature : 300 C or below, Heat time : 3 seconds or less (per pin)
Cautions 1. 2.
During assembly care should be taken to prevent solder or flux from contacting the plastic cap. The optical characteristics could be degraded by such contact. Soldering by the solder flow method may have deleterious effects on prevention of plastic cap soiling and heat resistance. So the method cannot be guaranteed.

NOTES ON HANDLING THE PACKAGES
1 DUST AND DIRT PROTECTING
The optical characteristics of the CCD will be degraded if the cap is scratched during cleaning. Don't either touch plastic cap surface by hand or have any object come in contact with plastic cap surface. Should dirt stick to a plastic cap surface, blow it off with an air blower. For dirt stuck through electricity ionized air is recommended. And if the plastic cap surface is grease stained, clean with our recommended solvents.
CLEANING THE PLASTIC CAP
Care should be taken when cleaning the surface to prevent scratches. We recommend cleaning the cap with a soft cloth moistened with one of the recommended solvents below. Excessive pressure should not be applied to the cap during cleaning. If the cap requires multiple cleanings it is recommended that a clean surface or cloth be used.
RECOMMENDED SOLVENTS
The following are the recommended solvents for cleaning the CCD plastic cap. Use of solvents other than these could result in optical or physical degradation in the plastic cap. Please consult your sales office when considering an alternative solvent. Solvents Ethyl Alcohol Methyl Alcohol Isopropyl Alcohol N-methyl Pyrrolidone Symbol EtOH MeOH IPA NMP
2 MOUNTING OF THE PACKAGE
The application of an excessive load to the package may cause the package to warp or break, or cause chips to come off internally. Particular care should be taken when mounting the package on the circuit board. Don't have any object come in contact with plastic cap. You should not reform the lead frame. We recommended to use a IC-inserter when you assemble to PCB. Also, be care that the any of the following can cause the package to crack or dust to be generated. 1. Applying heat to the external leads for an extended period of time with soldering iron. 2. Applying repetitive bending stress to the external leads. 3. Rapid cooling or heating
3 OPERATE AND STORAGE ENVIRONMENTS
Operate in clean environments. CCD image sensors are precise optical equipment that should not be subject to mechanical shocks. Exposure to high temperatures or humidity will affect the characteristics. So avoid storage or usage in such conditions. Keep in a case to protect from dust and dirt. Dew condensation may occur on CCD image sensors when the devices are transported from a low-temperature environment to a high-temperature environment. Avoid such rapid temperature changes. For more details, refer to our document "Review of Quality and Reliability Handbook" (C12769E)
4 ELECTROSTATIC BREAKDOWN
CCD image sensor is protected against static electricity, but destruction due to static electricity is sometimes detected. Before handling be sure to take the following protective measures. 1. Ground the tools such as soldering iron, radio cutting pliers of or pincer. 2. Install a conductive mat or on the floor or working table to prevent the generation of static electricity. 3. Either handle bare handed or use non-chargeable gloves, clothes or material. 4. Ionized air is recommended for discharge when handling CCD image sensor. 5. For the shipment of mounted substrates, use box treated for prevention of static charges. 6. Anyone who is handling CCD image sensors, mounting them on PCBs or testing or inspecting PCBs on which CCD image sensors have been mounted must wear anti-static bands such as wrist straps and ankle straps which are grounded via a series resistance connection of about 1 M.

NOTES FOR CMOS DEVICES
1 VOLTAGE APPLICATION WAVEFORM AT INPUT PIN Waveform distortion due to input noise or a reflected wave may cause malfunction. If the input of the CMOS device stays in the area between VIL (MAX) and VIH (MIN) due to noise, etc., the device may malfunction. Take care to prevent chattering noise from entering the device when the input level is fixed, and also in the transition period when the input level passes through the area between VIL (MAX) and VIH (MIN). 2 HANDLING OF UNUSED INPUT PINS Unconnected CMOS device inputs can be cause of malfunction. If an input pin is unconnected, it is possible that an internal input level may be generated due to noise, etc., causing malfunction. CMOS devices behave differently than Bipolar or NMOS devices. Input levels of CMOS devices must be fixed high or low by using pull-up or pull-down circuitry. Each unused pin should be connected to VDD or GND via a resistor if there is a possibility that it will be an output pin. All handling related to unused pins must be judged separately for each device and according to related specifications governing the device. 3 PRECAUTION AGAINST ESD A strong electric field, when exposed to a MOS device, can cause destruction of the gate oxide and ultimately degrade the device operation. Steps must be taken to stop generation of static electricity as much as possible, and quickly dissipate it when it has occurred. Environmental control must be adequate. When it is dry, a humidifier should be used. It is recommended to avoid using insulators that easily build up static electricity. Semiconductor devices must be stored and transported in an anti-static container, static shielding bag or conductive material. All test and measurement tools including work benches and floors should be grounded. The operator should be grounded using a wrist strap. Semiconductor devices must not be touched with bare hands. Similar precautions need to be taken for PW boards with mounted semiconductor devices. 4 STATUS BEFORE INITIALIZATION Power-on does not necessarily define the initial status of a MOS device. Immediately after the power source is turned ON, devices with reset functions have not yet been initialized. Hence, power-on does not guarantee output pin levels, I/O settings or contents of registers. A device is not initialized until the reset signal is received. A reset operation must be executed immediately after power-on for devices with reset functions. 5 POWER ON/OFF SEQUENCE In the case of a device that uses different power supplies for the internal operation and external interface, as a rule, switch on the external power supply after switching on the internal power supply. When switching the power supply off, as a rule, switch off the external power supply and then the internal power supply. Use of the reverse power on/off sequences may result in the application of an overvoltage to the internal elements of the device, causing malfunction and degradation of internal elements due to the passage of an abnormal current. The correct power on/off sequence must be judged separately for each device and according to related specifications governing the device. 6 INPUT OF SIGNAL DURING POWER OFF STATE Do not input signals or an I/O pull-up power supply while the device is not powered. The current injection that results from input of such a signal or I/O pull-up power supply may cause malfunction and the abnormal current that passes in the device at this time may cause degradation of internal elements. Input of signals during the power off state must be judged separately for each device and according to related specifications governing the device.
