Description

1

VCC

Power Supply, 5 V ± 10%.

2

RO

Receiver Output. When A > B by 200 mV, RO = high. If A < B by 200 mV, RO = low.

3

DI

Driver Input. A logic low on DI forces Y low and Z high, whereas a logic high on DI forces Y high and Z low.

4

GND

Ground Connection, 0 V.

5

Y

Noninverting Driver, Differential Output Y.

6

Z

Inverting Driver, Differential Output Z.

7

B

Inverting Receiver, Input B.

8

A

Noninverting Receiver, Input A.
