DS26C31T/DS26C31M CMOS Quad TRI-STATE

Differential Line Driver

Check for Samples: DS26C31M, DS26C31T

FEATURES

DESCRIPTION

The DS26C31 is a quad differential line driver

• TTL Input Compatible

designed for digital data transmission over balanced

• Typical Propagation Delays: 6 ns

lines. The DS26C31T meets all the requirements of

• Typical Output Skew: 0.5 ns

EIA standard RS-422 while retaining the low power

characteristics of CMOS. The DS26C31M is

• Outputs Will Not Load Line when V

= 0V

compatible with EIA standard RS-422; however, one

• DS26C31T Meets the Requirements of EIA

exception in test methodology is taken

(1)

. This

Standard RS-422

enables the construction of serial and terminal

• Operation from Single 5V Supply

interfaces while maintaining minimal power

consumption.

• TRI-STATE Outputs for Connection to System

Buses

The DS26C31 accepts TTL or CMOS input levels and

translates these to RS-422 output levels. This part

• Low Quiescent Current

uses special output circuitry that enables the drivers

• Available in Surface Mount

to power down without loading down the bus. This

• Mil-Std-883C Compliant

device has enable and disable circuitry common to all

four drivers. The DS26C31 is pin compatible to the

AM26LS31 and the DS26LS31.

All inputs are protected against damage due to

electrostatic discharge by diodes to V

and ground.

(1) The DS26C31M (−55°C to +125°C) is tested with V

OUT

between +6V and 0V while RS-422A condition is +6V and

−0.25V.
