Pin Symbol

Name and function

1

RO

Receiver output. If A>B by 200 mV, RO is high; if A< B by 200 mV, RO is low.

2

RE

Receiver output enable. RO is enabled when RE is low; RO is high impedance when RE is high. If RE is high

and DE is low, the device enters a low power shutdown mode.

3

DE

Driver output enable. The driver outputs are enabled by bringing DE high. They are high impedance when DE

is low. If RE is high DE is low, the device enters a low-power shutdown mode. If the driver outputs are enabled,

the part functions as line driver, while they are high impedance, it functions as line receivers if RE is low.

4

DI

Driver input. A low on DI forces output A low and output B high. Similarly, a high on DI forces output A high and

output B low.

5

GND

Ground

6

A

Non-inverting receiver input and non-inverting driver output.

7

B

Inverting receiver input and inverting driver output.

8

VCC

Supply voltage: VCC=3 V to 3.6 V.
