Overview
The SN75182NE4, produced by Texas Instruments, is a dual differential line receiver designed to sense small differential signals in the presence of large common-mode noise. This device is part of the SN75182 series, which provides TTL-compatible output signals based on the polarity of the differential input voltage. The SN75182NE4 is characterized for operation from 0°C to 70°C, making it suitable for a variety of industrial and commercial applications. Although the SN75182 series is now obsolete, it remains relevant for legacy systems and maintenance purposes.
