IRED cathode, internally connected to driver transistor
Transmit Data Input
Received Data Output, push–pull CMOS driver output capable of driving a
standard CMOS or TTL load. No external pull–up or pull–down resistor is
required (20 k resistor internal to device). Pin is inactive during
transmission.
