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.
