Maxim Integrated (MAX3221CAE+) RS232 Transmitter/Receiver

Product Overview The MAX3221CAE+ 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. Integrated charge pump circuitry simplifies power requirements 1µA Supply current in shutdown mode saves power Applications Power Management, Computers & Computer Peripherals, Medical Product Information Device Type: Transceiver IC Interface Type: RS232 No. of Drivers: 1Drivers No. of Receivers: 1Receivers Supply Voltage Min: 3V Supply Voltage Max: 5.5V Driver Case Style: SSOP No. of Pins: 16Pins Operating Temperature Min: 0°C Operating Temperature Max: 70°C Product Range: - Automotive Qualification Standard: - MSL: MSL 1 - Unlimited
