The MAX3221EAE+ is a RS-232 Transceiver for handheld equipment. The MAX3221 achieve 1µA supply current with Maxim"s revolutionary AutoShutdown™ feature. When the MAX3221 do 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. The MAX3221 require only 0.1µF capacitors in 3.3V operation and can operate from input voltages ranging from +3.0 to +5.5V. A proprietary, high-efficiency, dual charge-pump power supply and a low-dropout transmitter combine to deliver true RS-232 performance from a single +3.0 to +5.5V supply.
The MAX3221EIPW is a 3 to 5.5V single-channel RS-232 Line Driver/Receiver features one driver and one receiver. This driver/receiver operates with 3 to 5.5V VCC supply and It has auto-power down feature which automatically disables drivers for power savings. Accepts 5V logic input with 3.3V supply.Expand
