Working Principles

The SN65HVD251DRG4 is a half-duplex transceiver that uses differential signaling to transmit and receive data. It operates by converting the digital signals from a microcontroller into differential voltage levels suitable for transmission over a bus line. The receiver section of the transceiver converts the received differential signals back into digital data.
