Working Principles

The SN75ALS172AN is designed to transmit and receive digital signals over long distances. It utilizes differential signaling, where the transmitted signal is represented by the voltage difference between two lines. This allows for better noise immunity and improved signal integrity.

The IC operates by converting the input digital signals into differential output signals using internal drivers. The receiver section then converts the received differential signals back into digital logic levels. The control inputs enable/disable the driver and receiver functions as needed.
