NAME

FUNCTION

1

B1

Inverting Receiver Input

2

A1

Noninverting Receiver Input

PIN

3

Y1

Receiver Output. Enabled when G = high OR G = low. Y1 will be logic high if A1 > B1 by 200mV, and low if

A1 < B1 by 200mV. It will be logic high if A1 and B1 remain floating. Otherwise, the state is undetermined.

Y1 goes high impedance when the G = low

and G = high.

4

G

Receiver Output Enable High. A logic high on this input enables all receivers. When taken low and G is high,

all receivers are shut down, and the outputs go high impedance.

8

GND

Ground

7

B2

Inverting Receiver Input

6

A2

Noninverting Receiver Input

5

Y2

Receiver Output. Same functionality as Y1.

13

Y4

Receiver Output. Same functionality as Y1.

12

G

Receiver Output Enable Low. A logic low on this pin enables all receivers. When G = high and G = low, all

receivers are shut down, and the outputs go high impedance.

11

Y3

Receiver Output. Same functionality as Y1.
