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  
multipointbustransmissionatdataratesuptoand  
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 LinBiCMOS 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.
