MAX3221CAE

Product Summary

The MAX3221CAE is a Transceiver. The MAX3221CAE achieves 1μA supply current with Maxim’s revolutionary AutoShutdown feature. When the MAX3221CAE 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 saves power without changes to the existing BIOS or operating system. The applications of the MAX3221CAE include Notebook, Subnotebook, and Palmtop Computers, Battery-Powered Equipment, Hand Held, Equipment, Peripherals, Printers.
