Working Principles

The SN75115D is a line driver/receiver integrated circuit that converts TTL/CMOS logic levels to differential signals and vice versa. It operates by receiving TTL/CMOS level inputs on pins A and B, and converting them into differential outputs on pins Y and Z. The driver and receiver sections can be independently enabled or disabled using the DE and RE inputs, respectively. The device also incorporates fail-safe circuitry to ensure that an open input does not result in false output signals.
