R1out and R2out

Receiver output pins are TTL/CMOS compatible

10, 11

Tin1, Tin2

Transmitter input pins are TTL/CMOS compatible. Inputs of transmitter do not have pull-up resistors.

Connect all unused transmitter inputs to ground

GND

Ground pin

16

Power supply pin for the device, +5V (±10%)

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam

during storage or handling to prevent electrostatic damage to the MOS gates.
