Product Summary

The MAX3243IDBR is a 1μA Supply-Current, True +3V to +5.5V RS-232 Transceiver with AutoShutdown. The MAX3243IDBR achieves 1μA supply current with Maxim revolutionary AutoShutdown feature. When the MAX3243IDBR does not sense a valid signal level on its receiver inputs, 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 turned off. The applications of the MAX3243IDBR include Notebook, Subnotebook, and Palmtop Computers, Battery-Powered Equipment, Hand-Held Equipment, Peripherals and Printers.
