Description

IRED anode, to be externally connected

to VCC through a current control resistor.

This pin is allowed to be supplied from

an uncontrolled power supply separated

from the controlled VCC supply

IRED cathode, internally connected to

driver transistor

Transmit Data Input

Received Data Output, push-pull CMOS

driver output capable of driving a stan-

dard CMOS or TTL load. No external

pull-up or pull-down resistor is required.

Pin is floating when

device is in shutdown mode
