Working Principles

The SN75188N is a line driver/receiver IC designed for bidirectional data communication. It operates by receiving TTL-level input signals on the A and B pins, and transmitting them through the Y and Z pins. The receiver section of the IC detects incoming signals and provides a corresponding output on the RO pin. The driver section amplifies the input signal received on the DI pin and transmits it through the Y pin.
