TXD

LED Anode Tied through external resistor,R1,to regulated

Vcc from 2.7 to 6 Volts.

Transmitter Logic High turn on the IrED.

RXD

Receiver Data Output is a low pulse when a light pulse is seen.

Output

Vcc

Shut Down Must be driven either high or low.

Supply Voltage Supply Voltage from 2.7 to 6 Volts.

GND

Ground

Connect to system ground

SHIELD

EMI Shield Connect to system ground via a low inductance

trace. For best performance, do not connect to

GND directly at the part.

TRANSCEIVER I/O Truth Table

The LED and RXD outputs are controlled by the combination of the TXD and SD pins and

light falling on the receiver.As shown in the table below,the transmitteris non-inverting ;the LED is

on when the TXD pin is high and off when TXD is low.The receiver is inverting;the RXD pin is

low during IrDA signal pulses and high when the receiver does not see any light.When

shutdown(SD pin high),the LED is off(the state of the TXD pin does not matter),and the RXD pin is

pulled high with a weak internal pullup.
