The SN55115 and SN75115 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 differential input  
voltage. The open-collector output configuration  
permits the wire-ANDing of similar TTL outputs

or  
other  
NC – No internal connection  
SN55115/SN75115 line receivers. This permits a  
level of logic to be implemented without extra  
delay.  
The output stages are similar to TTL totem-pole outputs, but with sink outputs, 1YS and 2YS, and the  
corresponding active pullup terminals, 1YP and 2YP, available on adjacent package pins. The frequency  
response and noise immunity may be provided by a single external capacitor. A strobe input is provided for each  
channel. With the strobe in the low level, the receiver is disabled and the outputs are forced to a high level.  
The SN55115 is characterized for operation over the full military temperature range of 55°C to 125°C. The  
SN75115 is characterized for operation from 0°C to 70°C.
