Working Principles

The SN75176BPS is a differential bus transceiver that enables bidirectional data communication between two buses. It operates based on the RS-485 and RS-422 standards, allowing for reliable data transmission over long distances.

The transceiver uses differential signaling to transmit and receive data, which provides noise immunity and reduces the effects of electromagnetic interference. It supports half-duplex communication, meaning that data can be transmitted in one direction at a time.

The device incorporates fail-safe circuitry, which ensures that the bus remains in a known state when no driver is actively transmitting. This feature prevents bus contention and minimizes the risk of data corruption.
