description
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.
