Description
The ZILOG ZHX1810 is a low-profile version of ZiLOG's popular ZHX1010 1-meter transceiver. The transceiver is mechanically enhanced for ultra compact, power-conscious portable products, such as mobile phones, portable printers, handheld computers, and personal data assistants (PDAs). Designed to operate using the IrDA-Data mode, the transceiver combines an infrared emitting diode (IRED) emitter, a PIN photodiode detector, a digital AC coupled LED driver, and a receiver/decoder in a single package. The ZILOG ZHX1810 provides an efficient implementation of the SIR standard in a small-outline footprint format. Application circuit space is also minimized, as only three components are required. ZHX1810 also features an independently controlled shutdown that minimizes current draw to a maximum of 1 mA.

LEDA LED Driver Anode
(Power) This output is connected to the LED anode. Current to the LED is sourced through an external resistor.
TXD Transmit Data
(Input, active high) This CMOS input is used to transmit serial data. This input has an internal pulldown resistor that is disabled (open-circuited) during shutdown.
RXD/Receive Data
(Output, active low) This output indicates received serial data. It is a tri-state, slew rate controlled CMOS output (tri-stated during shutdown) driver capable of driving a standard CMOS load. No external resistor is required.
SD Shutdown
(Input, active high) This input is used to place the integrated circuit into shutdown mode. Module shutdown current is influenced by the choice of capacitor used from VCC to ground.
VCC Positive Supply
(Power) Connect to positive power supply (2.4-5.5 V). Filter with a 0.33-mF ceramic bypass capacitor and terminating resistor as close as possible to the VCC pin.
GND Ground
(Power) Connect to ground of the power supply. A solid ground plane is recommended for proper operation.
TAB
(Shield) The Shield tab must be soldered to the ground plane.

Mechanical Drawings
In order to achieve the lowest possible lead times, ZiLOG maintains two assembly facilities. The mechanical drawings for these transceivers are shown in Figure 7 and Figure 8. These devices, which show minor mechanical differences, are functionally equivalent in every way and meet all ZiLOG and IrDA standards and specifications. Although reels are never mixed, ZiLOG reserves the right to ship from either facility in order to meet delivery requirements.

Packing, Storage, and Baking Recommendations
Follow these recommendations to maintain the performance of the ZHX1810 transceiver.
Storage
To avoid moisture absorption, ZHX1810 reels must remain in the original, unopened moisture-proof packing. Parts must be soldered within 72 hours after unpacking. Reels that have been unpacked, but will not be soldered within 72 hours, must be stored in a desiccator.
Baking
Parts that have been stored over 12 months or unpacked over 72 hours must be baked under the following guidelines. Reels 60 C for 48 hours or more Loose Parts
* * *
100 C for 4 hours or more or 125 C for 2 hours or more or 150 C for 1 hour or more

Moisture-Proof Packing
In order to avoid moisture absorption during transportation and storage, ZHX1810 reels are packed in aluminum envelopes (see Figure 10) that contain a desiccant with a humidity indicator. While this packaging is an impediment to moisture absorption, it is by no means absolute, and no warranty is implied. The user should store these parts in a controlled environment to prevent moisture entry. Please read the label on the aluminum bag for indicator instructions.
