Overview
The SN75183N, produced by Texas Instruments, is a dual differential line driver designed to provide high-current capability for driving balanced lines such as twisted pairs. This device is part of a family that includes the DS8830 and SN55183, all of which are characterized by their ability to operate with a single 5-V supply and offer TTL compatibility. The SN75183N is particularly suited for applications requiring differential line operation without high power dissipation.
