📥 Download Datasheet

General Description

The SN55LBC173 is a monolithic quadruple differential line receiver with 3-state outputs 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.

Overview

Key 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. FK.
