Working Principles

The SN75173D is designed to transmit and receive digital signals using differential signaling. It operates by comparing the voltage difference between two input pins (A and B) and generating corresponding output signals (Y and Z). The enable inputs control the driver and receiver sections, allowing for selective operation.

When transmitting data, the driver section amplifies the differential input signal and drives it onto the transmission line. On the receiving end, the receiver section detects the differential voltage and converts it back into a digital signal.
