Working Principles

The TRSF3222CPWR is a dual-channel RS-232 transceiver that enables bidirectional serial communication between devices. It utilizes an integrated charge pump to convert the logic-level signals to RS-232 voltage levels, allowing compatibility with RS-232 standard. The transceiver features hysteresis on the receiver inputs, which improves noise immunity and ensures reliable data reception. Additionally, it incorporates an auto-power-down feature that reduces power consumption when not actively transmitting or receiving data.
