Product Summary

The MAX3243ECUI achieves 1μA supply current with Maxim revolutionary AutoShutdown feature. When the MAX3243ECUI does not sense a valid signal level on their 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 system turns on again when a valid level is applied to any RS-232 receiver input. As a result, the system of the MAX3243ECUI saves power without changes to the existing BIOS or operating system. The MAX3243ECUI transceiver is 3V powered EIA/TIA-232 and V.28/V.24 communications interfaces intended for notebook computer applications.
