Working Principles

The SN65LBC172ADW is designed to transmit and receive data over balanced transmission lines. It uses differential signaling, where the transmitted data is represented by the voltage difference between two lines. This allows for high noise immunity and reliable data transmission over long distances.

The driver section of the IC amplifies the input signal and converts it into a balanced output signal. The receiver section receives the balanced signal and converts it back into a digital output. The driver and receiver can be enabled or disabled independently, providing flexibility in controlling the communication link.
