Working Principles

The SN75185DWRE4 is a differential line driver and receiver IC that enables bidirectional communication between two voltage systems. It uses differential signaling to transmit and receive data, which provides better noise immunity compared to single-ended signaling. The receiver input hysteresis helps reject noise and ensures reliable data reception. The driver output current limiting and thermal shutdown protection prevent damage to the IC and connected devices in case of excessive current or temperature.
