DESCRIPTION/ORDERING INFORMATION
The SN55182 dual differential line receiver is
designed to sense small differential signals in the
presence of large common-mode noise. This device
gives 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.
