Working Principles

The SN65LBC182D is a transceiver IC that uses differential signaling to transmit data between two devices. It operates by converting parallel data into a differential signal and vice versa. The differential signals provide noise immunity and allow for long-distance communication.

When transmitting data, the driver input (DI) receives parallel data and converts it into a differential signal. The driver enable (DE) pin controls the transmission of data. On the receiving end, the receiver output (RO) provides the received data in parallel form. The receiver enable (RE) pin enables or disables the receiver.
