The SN55182 and SN75182 dual differential line  
receivers are designed to sense small differential  
signals in the presence of large common-mode  
noise. These devices give TTL-compatible output  
signals as a function of the polarity of the  
differential input voltage. The frequency response  
of each channel can be easily controlled by a  
single external capacitor to provide immunity to  
differential noise spikes. The output goes to a high  
level when the inputs are open circuited. A strobe  
input (STRB) is provided that, when in the low  
level, disables the receiver and forces the output  
to a high level.

THE SN55182 IS NOT RECOMMENDED  
FOR NEW DESIGNS  
The receiver is of monolithic single-chip construction, and both halves of the dual circuits use common  
power-supply and ground terminals.  
The SN55182 is characterized for operation over the full military temperature range of –55°C to 125°C. The  
SN75182 is characterized for operation from 0°C to 70°C.
