A quad differential line driver integrated circuit (IC) called the AM26C31IPW is intended for use in digital communication systems. RS-422/RS-485 communication, industrial automation, motor control, instrumentation, security systems, and audio and video equipment are just a few of the applications where it is frequently utilized. Four distinct transmission lines can be driven by the IC's four independent differential line drivers. It makes use of differential outputs, which have a strong common-mode noise rejection and lower the system's EMI. The AM26C31IPW has a maximum data rate of 20 Mbps and can operate over a wide voltage range of 4.5 V to 5.5 V.
