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 V_CC and ground.

Features

TTL input compatible
Typical propagation delays: 6 ns
Typical output skew: 0.5 ns
Outputs won't load line when V_CC = 0V
Meets the requirements of EIA standard RS-422
Operation from single 5V supply
TRI-STATE outputs for connection to system buses
Low quiescent current
Available in surface mount
