DESCRIPTION

The DS26C31 is a quad differential line driver

designed for digital data transmission over balanced

lines. The DS26C31 meets all the requirements of

EIA standard RS-422 while retaining the low power

characteristics of CMOS. The DS26C31 is compatible

with EIA standard RS-422; however, one exception in

test methodology is taken. This enables the

construction of serial and terminal interfaces while

maintaining minimal power consumption.

The DS26C31 accepts TTL or CMOS input levels and

translates these to RS-422 output levels. This part

uses special output circuitry that enables the drivers

to power down without loading down the bus. This

device has enable and disable circuitry common to all

four drivers. The DS26C31 is pin compatible to the

AM26LS31 and the DS26LS31.

All inputs are protected against damage due to

electrostatic discharge by diodes to VCC and ground.
