Texas Instruments (MAX3222CDBR) Transceiver RS232, 2 Drivers

Product OverviewThe MAX3222CDBR is a RS-232 multichannel Line Driver/Receiver with ±15kV ESDprotection pin-to-pin (serial-port connection pins, including GND). The devicemeets the requirements of TIA/EIA-232-F and provides the electrical interfacebetween an asynchronous communication controller and the serial-port connector.The charge pump and four small external capacitors allow operation from a single3 to 5.5V supply. The device operates at data signalling rates up to 250kbps anda maximum of 30V/µs driver output slew rate. It can be placed in the power-downmode by setting PWRDOWN low, which draws only 1µA from the power supply. Whenthe device is powered down, the receivers remain active while the driver isplaced in the high-impedance state. Also, during power-down, the onboard chargepump is disabled, V+ is lowered to VCC and V- is raised toward GND. Receiveroutputs also can be placed in the high-impedance state by setting EN high.Alternative high-speed pin-compatible device (1Mbps) for SNx5C32221µA Typical Low standby currentGreen product and no Sb/BrApplicationsPortable Devices, Computers & Computer PeripheralsProduct InformationDevice Type: RS232 TransceiverIC Interface Type: RS232No. of Drivers: 2DriversNo. of Receivers: 2ReceiversSupply Voltage Min: 3VSupply Voltage Max: 5.5VDriver Case Style: SSOPNo. of Pins: 20PinsOperating Temperature Min: 0°COperating Temperature Max: 70°CProduct Range: -Automotive Qualification Standard: -MSL: MSL 1 - Unlimited
