Overview
The SN75182 dual differential line receiver, produced by Texas Instruments, is designed to sense small differential signals in the presence of large common-mode noise. This device provides TTL-compatible output signals based on the polarity of the differential input voltage. It is particularly useful in environments where noise immunity is crucial. The SN75182 operates on a single 5-V supply and is characterized for operation from 0°C to 70°C, making it suitable for a variety of industrial and commercial applications.
