www.ti.com SNOSAS2A – OCTOBER 2010 – REVISED APRIL 2013 DS26C31MQML CMOS Quad TRI-STATE Differential Line Driver
Check for Samples: DS26C31MQML FEATURES DESCRIPTION The DS26C31 is a quad differential line driver
designed for digital data transmission over balanced
lines. The DS26C31 meets all the requirements of
EIA standard RS-422 while retaining the low power
characteristics of CMOS. The DS26C31 is compatible
with EIA standard RS-422; however, one exception in
test methodology is taken. This enables the
construction of serial and terminal interfaces while
maintaining minimal power consumption. 1 2 TTL Input Compatible
Outputs Will Not Load Line When VCC = 0V
Meets the Requirements of EIA Standard RS422
Operation from Single 5V Supply
TRI-STATE Outputs for Connection to System
Buses
Low Quiescent Current The DS26C31 accepts TTL or CMOS input levels and
translates these to RS-422 output levels. This part
uses special output circuitry that enables the drivers
to power down without loading down the bus. This
device has enable and disable circuitry common to all
four drivers. The DS26C31 is pin compatible to the
AM26LS31 and the DS26LS31. …
