high, the driver outputs will be fed back to the receiver and

the receive output will correspond to the driver input.

DI (Pin 4): Driver Input. If the driver outputs are enabled

(DE HIGH) then a low on DI forces the outputs A LOW and

B HIGH. A HIGH on DI with the driver outputs enabled will

force A HIGH and B LOW.

GND (Pin 5): Ground.

A (Pin 6): Driver Output/Receiver Input.

B (Pin 7): Driver Output/Receiver Input.

RO (Pin 1): Receiver Output. If the receiver output is

enabled (RE LOW) and A > B by 200mV, then RO will be

HIGH. If A < B by 200mV, then RO will be LOW.

RE (Pin 2): Receiver Output Enable. A LOW enables the

receiver output, RO. A HIGH input forces the receiver

output into a high impedance state.

DE (Pin 3): Driver Outputs Enable. A HIGH on DE enables

the driver output. A, B and the chip will function as a line

driver. A low input will force the driver outputs into a high

impedance state and the chip will function as a line

receiver. If RE is high and DE is LOW, the part will enter a

low power (1

µA) shutdown state. If RE is low and DE is
