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.
