description

The SN55LBC173 is a monolithic quadruple

differential line receiver with 3-state outputs and is

designed to meet the requirements of the EIA

standards RS-422-A, RS-423-A, RS-485, and

CCITT V.11. This device is optimized for balanced

multipoint bus transmission at data rates up to and

exceeding 10 million bits per second. The four

receivers share two ORed enable inputs, one

active when high, the other active when low. Each

receiver features high input impedance, input

hysteresis for increased noise immunity, and input

sensitivity of

±200 mV over a common-mode input

voltage range of 12 V to –7 V. Fail-safe design

ensures that if the inputs are open circuited, the

output is always high. The SN55LBC173 is

designed using the Texas Instruments proprietary

LinBiCMOS

™ technology that provides low power

consumption,

high

switching

speeds,

and

robustness.

This device offers optimum performance when used with the SN55LBC172M quadruple line driver. The

SN55LBC173 is available in the 16-pin CDIP (J), the 16-pin CPAK (W), or the 20-pin LCCC (FK) packages.

The SN55LBC173 is characterized over the military temperature range of – 55

°C to 125°C.
