About this manual

The MAX3223 is a dual-channel RS-232 transceiver designed for battery-powered systems such as PDAs, notebooks, and hand-held equipment. It integrates two line drivers, two line receivers, and a dual charge-pump circuit with +15-kV ESD protection to interface asynchronous communication controllers with serial-port connectors.

The device operates from a single 3-V to 5.5-V supply voltage and supports data signaling rates up to 250 kbit/s. It features flexible power management options, including an auto-powerdown mode that disables driver outputs when no valid RS-232 signal is sensed, reducing supply current to approximately 1 µA.
