PIN NAME

DESCRIPTION

1

RO

Receiver output.

2

RE

Receiver output enable. Drive RE low to enable RO; RO is high impedance when RE

is high. Drive RE high and DE low to enter low-power shutdown mode.

3

DE

Driver output enable. Drive DE high to enable driver outputs. These outputs are high

impedance when DE is low. Drive RE high and DE low to enter low-power shutdown

mode.

4

DI

Driver input. With DE high, a low on DI forces non-inverting output low and inverting

output high. Similarly, a high on DI forces non-inverting output high and inverting output

low.

5

GND

Ground

6

A

Non-inverting receiver input and non-inverting driver output

7

B

Inverting receiver input and inverting driver output
