Working Principles

The SN65LBC180N is a transceiver IC that enables bidirectional communication between two devices using differential signaling. It consists of a receiver and a driver section. The receiver converts the incoming differential signals into logic-level outputs, while the driver section converts logic-level inputs into differential signals for transmission.

When the receiver enable (/RE) pin is low, the receiver is enabled, allowing it to receive and process incoming signals. Conversely, when the driver enable (DE) pin is low, the driver is enabled, allowing it to transmit signals.

The differential signaling used by the SN65LBC180N provides noise immunity and allows reliable communication over long distances. By using differential pairs, the IC can effectively reject common-mode noise, ensuring accurate data transmission.
