DS34C87T

CMOS Quad TRI-STATE Differential Line Driver

General Description

Features

n TTL input compatible

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.

n Typical propagation delays: 6 ns

n Typical output skew: 0.5 ns

n Outputs won’t load line when V_CC= 0V

n Meets the requirements of EIA standard RS-422

n Operation from single 5V supply

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.

n TRI-STATE outputs for connection to system buses

n Low quiescent current

n Available in surface mount

All inputs are protected against damage due to electrostatic

discharge by diodes to V_CCand ground.
