1

IRED Anode

separate power supply can be used at this pin.

2

IRED Cathode

IRED Cathode, internally connected to driver transistor

3

TxD

Transmit Data Input

I

HIGH

4

RxD

Received Data Output, capable of driving a standard CMOS or TTL

load. No external pull-up or pull-down resistor is required. Pin is

floating when device is in shutdown mode and is not quiet during

data transmission.

O

LOW

SD/ Mode

Places the device in shutdown mode and switches bandwidth

together with TxD
