CAUTION: It is advised that normal static precautions be taken in handling and assembly of this component to prevent damage and/or degradation which may be induced by ESD. 1-288 5965-3587E
characteristics enable this device to be used in an RS-232-C interface with ground loop isolation and improved common mode rejection. As a line receiver, the HCPL-2300 will operate over longer line lengths for a given data rate because of lower IF and VF specifications. The output of the shielded integrated detector circuit is an open
collector Schottky clamped transistor. The shield, which shunts capacitively coupled common mode noise to ground, provides a guaranteed transient immunity specification of 100 V/s. The output circuit includes an optional integrated 1000 pullup resistor for the open collector. This gives designers the flexibility to use the internal resistor for pull-up to five volt logic or to use
an external resistor for connection to supply voltages up to 18 V (CMOS logic voltage). The Electrical and Switching Characteristics of the HCPL-2300 are guaranteed over a temperature range of -40C to 85C. This enables the user to confidently design a circuit which will operate under a broad range of operating conditions.

*The Input-Output Momentary Withstand Voltage is a dielectric voltage rating that should not be interpreted as an input-output continuous voltage rating. For the continuous voltage rating refer to the VDE 0884 Insulation Characteristics Table (if applicable), your equipment level safety specification, or HP Application Note 1074, "Optocoupler Input-Output Endurance Voltage."
Notes: 1. Bypassing the power supply line is required with a 0.1 F ceramic disc capacitor adjacent to each optocoupler as illustrated in Figure 19. The power supply bus for the optocoupler(s) should be separate from the bus for any active loads, otherwise a larger value of bypass capacitor (up to 0.5 F) may be needed to suppress regenerative feedback via the power supply. 2. Peaking circuits may produce transient input currents up to 100 mA, 500 ns maximum pulse width, provided average current does not exceed 5 mA.
3. Device considered a two terminal device: pins 1, 2, 3, and 4 shorted together, and pins 5, 6, 7, and 8 shorted together. 4. The tPLH propagation delay is measured from the 50% point on the trailing edge of the input pulse to the 1.5 V point on the trailing edge of the output pulse. 5. The tPHL propagation delay is measured from the 50% point on the leading edge of the input pulse to the 1.5 V point on the leading edge of the output pulse. 6. CMH is the maximum tolerable rate of rise of the common mode voltage to assure that the output will remain in a high logic state (i.e., VOUT > 2.0 V).
7. CML is the maximum tolerable rate of fall of the common mode voltage to assure that the output will remain in a low logic state (i.e., VOUT < 0.8 V). 8. CP is the peaking capacitance. Refer to test circuit in Figure 8. 9. In accordance with UL 1577, each optocoupler is momentary withstand proof tested by applying an insulation test voltage 3000 Vrms for 1 second (leakage detection current limit, II-O 5 A). This test is performed before the 100% production test for partial discharge (Method b) shown in the VDE 0884 Insulation Characteristics Table, if applicable.

circuits are illustrated in Figures 12-16, and 18 with corresponding component values, performance data and recommended layout in Figures 17 and 19. For -40C to 85C operating temperature range, a mid-range LED forward current (IF) of 0.625 mA is recommended in order to prevent overdriving the integrated circuit detector due to increased LED efficiency at temperatures between 0C and -40C. For narrower temperature range of 0C to 85C, a suggested operating LED current of 0.75 mA is recommended for the mid-range operating point and for minimal propagation delay skew. A peaking capacitance of 20 pF in parallel with the current limiting resistor for the LED shortens tPHL by approximately 33% and tPLH by 13%. Maintaining LED forward voltage (VF) below 0.8 V will guarantee that the HCPL-2300 output is off. The recommended shunt drive technique for TTL/LSTTL/CMOS of Figure 12 provides for optimal speed performance, no leakage current path through the LED, and reduced common mode influences associated with series
switching of a "floating" LED. Alternate series drive techniques with either an active CMOS inverter or an open collector TTL/ LSTTL inverter are illustrated in Figures 13 and 14 respectively. Open collector leakage current of 250 A has been compensated by the 3.16 K resistor (Figure 14) at the expense of twice the operating forward current. An application of the HCPL-2300 as an unbalanced line receiver for use in long line twisted wire pair communication links is shown in Figure 15. Low LED IF and VF allow longer line length, higher speed and multiple stations on the line in comparison to higher IF, VF optocouplers. Greater speed performance along with nearly infinite common mode immunity are achieved via the balanced split phase circuit of Figure 16. Basic balanced differential line receiver can be accomplished with one HCPL2300 in Figure 16, but with a typical 400 V/s common mode immunity. Data rate versus distance for both the above unbalanced and balanced line receiver applications are compared in Figure 17. The RS-232-C interface circuit of Figure 18

Applications
The HCPL-2300 optocoupler has the unique combination of low 0.5 mA LED operating drive current at a 5 MBd speed performance. Low power supply current requirement of 10 mA maximum at 5.25 V and the ability to provide isolation between logic systems fulfills numerous applications ranging from logic level translations, line receiver and party line receiver applications, microprocessor I/O port isolation, etc. The open collector output allows for wired-OR arrangement. Specific interface

provides guaranteed minimum common mode immunity of 100 V/s while maintaining the 2:1 dynamic range of IF. A recommended layout for use with an internal 1000 resistor
or an external pull-up resistor and required VCC bypass capacitor is given in Figure 19. VCC1 is used with an external pull-up resistor for output voltage levels (VO) greater than or equal to 5 V. As illustrated in Figure 19, an
optional VCC and GND trace can be located between the input and the output leads of the HCPL2300 to provide additional noise immunity at the compromise of insulation capability (VI-O).
