1

RO

Receiver Output. If A > B by 200mV, RO   will be high; if A < B by 200mV,RO will be low.

2

RE

Receiver Output Enable. RO is enabled   when RE is low; RO is high imped-ance when REis high. If REis high and DE is   low, the device will enter alow-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 and DE is low, the device will enter a low-power shutdown mode. If   the driver outputs are enabled, the parts function as line drivers. While   they are high impedance, they function as line receivers if RE is low.

4

DI

Driver Input. A low on DI forces output Y   low and output Z high. Similarly, ahigh on DI forces output Y high and output   Z low.

5

GND

Ground

6

A

Noninverting Receiver Input and   Noninverting Driver Output

7

B

Inverting Receiver Input and Inverting   Driver Output

8

Vcc

Positive Supply: 3.0V ≤VCC≤3.6V. Do not operate device with   VCC> 3.6V.
