Working Principles

The SN65HVD256D is a transceiver that enables half-duplex communication between two devices. It uses a differential signaling scheme to transmit and receive data over a single communication line. The driver section converts the digital signals from the microcontroller into a differential voltage signal, while the receiver section converts the received differential voltage back into digital signals.

Detailed Application Field Plans
