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 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.

†
Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. All voltage values, except differential voltages, are with respect to network ground terminal.
2. Differential voltage values are at the noninverting terminal with respect to the inverting terminal.
