FEATURES

DESCRIPTION

The DS34C87T is a quad differential line driver

2

•

TTL Input Compatible

designed for digital data transmission over balanced

Typical Propagation Delays: 6 ns

lines. The DS34C87T meets all the requirements of

•

Typical Output Skew: 0.5 ns

EIA standard RS-422 while retaining the low power

characteristics

of

CMOS.

This

enables

the

construction of serial and terminal interfaces while

•

Meets the Requirements of EIA Standard RS-

maintaining minimal power consumption.

422

The DS34C87T accepts TTL or CMOS input levels

•

Operation from Single 5V Supply

and translates these to RS-422 output levels. This

•

TRI-STATE Outputs for Connection to System

part uses special output circuitry that enables the

Buses

individual drivers to power down without loading down

the bus. This device has separate enable circuitry for

Low Quiescent Current

each pair of the four drivers. The DS34C87T is pin

Available in Surface Mount

compatible to the DS3487T.

All inputs are protected against damage due to
