Working Principles

The SN65C3221EPWRE4 operates based on the RS-232 protocol, which is a standard for serial communication interfaces. It uses differential signaling to transmit and receive data between devices. The transceiver converts the logic-level signals from the transmitting device into RS-232 compliant voltage levels for transmission over long distances. On the receiving end, it converts the RS-232 signals back into logic-level signals for the receiving device.
