DS26C31T/DS26C31M

CMOS Quad TRI-STATE^®Differential Line Driver

All inputs are protected against damage due to electrostatic

discharge by diodes to V_CCand ground.

General Description

The DS26C31 is a quad differential line driver designed for

digital data transmission over balanced lines. The

DS26C31T meets all the requirements of EIA standard

RS-422 while retaining the low power characteristics of

CMOS. The DS26C31M is compatible with EIA standard

RS-422; however, one exception in test methodology is

taken (Note 8). This enables the construction of serial and

terminal interfaces while maintaining minimal power con-

sumption.

Features

n TTL input compatible

n Typical propagation delays: 6 ns

n Typical output skew: 0.5 ns

n Outputs will not load line when V_CC0V

n DS26C31T meets the requirements of EIA standard

RS-422

The DS26C31 accepts TTL or CMOS input levels and trans-

lates these to RS-422 output levels. This part uses special

output circuitry that enables the drivers to power down with-

out loading down the bus. This device has enable and dis-

able circuitry common to all four drivers. The DS26C31 is pin

compatible to the AM26LS31 and the DS26LS31.

n Operation from single 5V supply

n TRI-STATE outputs for connection to system buses

n Low quiescent current

n Available in surface mount

n Mil-Std-883C compliant
