Description
The ZILOG ZHX1423 for PDAs, internet appliances, medical electronics, and general-purpose interactive handheld devices is the smallest, lowest power, and highest functional standard-power (0-1 meter minimum range) transceiver available. The ZiLOG ZHX1423 features exclusive AlwaysOnTM technology that allows the transceiver to "listen" for an IrDA communication at a typical current of 6 A, allowing the default mode to be left on with negligible effect on the battery life. The UltraSlim form factor (7.3 mm long x 2.8 mm wide x 1.9 mm high) allows placement in virtually any small device. Application circuit space is also minimized because only two external components are required. The ZHX1423 is designed to support IrDA-Data SIR mode (115.2 Kbits/s) and provides typical data links with other standard-power IrDA transceivers up to 1.0 meter away. The transceiver combines an IRED emitter, a PIN photodiode, and a unique driver/control ASIC in a single package, as shown in Figure 1.
Figure 1. ZHX1423 Block Diagram
The ZILOG ZHX1423 also features a shutdown control that minimizes current draw to 0.1 A typical.

GND Ground
(Power) Connect to ground of the power supply. A solid ground plane is recommended for proper operation.
SD Shutdown
(Input, active high) This input is used to place the transceiver into a shutdown mode.
RXD Receive Data
(Output, active low) This output provides received serial data. It is a tri-state, slew rate controlled CMOS output (tri-stated during shutdown) driver capable of driving a standard CMOS or LS series TTL load. No external resistor is required.
TXD Transmit Data
(Input, active high) This CMOS input is used to transmit serial data and has an internal pull-down resistor that is enabled during shutdown.
LEDA LED Driver
(Output, active low) This output is internally connected to the LED anode and contains an internal current source. The voltage range on this pad is 2.2-4.2 volts.

Moisture Prevention Guidelines
To avoid moisture absorption during transportation and storage, ZHX1423 reels are packed in aluminum envelopes (see Figure 5) 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 must store these parts in a controlled environment to prevent moisture entry. Please read the label on the aluminum bag for indicator instructions.
Figure 5. ZHX1423 Packaging
Baking
Parts that have been stored over 12 months or unpacked over 72 hours should 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
