DESCRIPTION

1

RO

Receiver output.

2

REB

Receiver output enable: REB is low to enable the Receiver; REB is high to disable the

Receiver.

3

DE

Transmitter output enable: DE is high to enable the transmitter; DE is low to disable the

transmitter.

4

DI

Transmitter input: When DE is high, a low on DI forces An output low and B output high.

Similarly, a high on DI forces An output high and B output low.

5

GND

Ground pin. Must be connected to 0V.

6

A

Non-inverting receiver input and non-inverting transmitter output

7

B

Inverting receiver input and inverting transmitter output

8

VCC

Power supply input 5.0V.
