lowest power, and highest functional transceiver in its class.

Communication takes place at the low receive current consumption of 100 µA

(typical). The ZHX1223TB features only the low receive current consumption of

90 µA (typical).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 ZHX1223 is designed to support IrDA-Data SIR mode, which at 115 Kbits/s

provides the capability for the user to share phone numbers, addresses, and

notes as well as linking a PC to the internet via a mobile transceiver combines an IRED emitter, a photodiode, and a unique driver/control ASIC in a single package, as shown in Figure1.

(Power)Connect to ground of the power supply. A solid ground plane is recommended for

proper Shutdown(Input, active high)This input is used to place the transceiver into a shutdown 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 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
