DS34C87T CMOS Quad TRI-STATE Differential Line Driver

Check for Samples: DS34C87T

FEATURES

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.

•

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

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.

•

Operation from Single 5V Supply

TRI-STATE Outputs for Connection to System

Buses

•

Low Quiescent Current

Available in Surface Mount

All inputs are protected against damage due to

electrostatic discharge by diodes to V_CCand ground.
