description

The SN55LBC175 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

receivers are enabled in pairs with an active-high

enable input. Each differential receiver input

features high impedance, hysteresis for

increased noise immunity, and 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 outputs are always

high. This device is designed using the Texas

Instruments proprietary LinBiCMOSE technology

allowing low power consumption, high switching

speeds, and robustness.

This device offers optimum performance when used with the SN55LBC174 quadruple line driver. The

SN55LBC175 is available in the 16-pin CDIP (J) package, a 16-pin CPAK (W) package, or a 20-pin LCCC (FK)

package.

The SN55LBC175 is characterized over the military temperature range of –55°C to 125°C.
