Product Summary

The MAX3238EAI is a true RS-232 transceiver achieves a 1μA supply current with Maxim’s revolutionary AutoShutdown Plus feature. When the device does not sense a valid signal transition on either the receiver or transmitter inputs within 30sec, the on-board power supply and drivers shut down. This occurs if the RS-232 cable is disconnected or if the transmitters of the connected peripheral are inactive. The applications of the MAX3238EAI include Notebook, Subnotebook, and Palmtop, Computers, High-Speed Modems, Battery-Powered Equipment, Hand-Held Equipment, Peripherals, Printers.
