DESCRIPTION

The DS34C87T is a quad differential line driver

designed for digital data transmission over balanced

lines. The DS34C87T meets all the requirements of

EIA standard RS-422 while retaining the low power

characteristics of CMOS. This enables the

construction of serial and terminal interfaces while maintaining minimal power consumption.

The DS34C87T accepts TTL or CMOS input levels

and translates these to RS-422 output levels. This

part uses special output circuitry that enables the

individual drivers to power down without loading down

the bus. This device has separate enable circuitry for

each pair of the four drivers. The DS34C87T is pin

compatible to the DS3487T.

All inputs are protected against damage due to

electrostatic discharge by diodes to VCC and ground.
