Maxim Integrated (MAX3224EAP+) Transceiver RS232, 3V-5.5V supply

Product OverviewThe MAX3224EAP+ is a 1µA supply current, 250Kbps, 3V to 5.5V, RS232 transceiverwith AutoShutdown Plus in 20 pin SSOP package. The device is 3V poweredEIA/TIA-232 and V.28/V.24 communication interfaces with automaticshutdown/wakeup characteristics and high data rate capabilities. This deviceautomatically enters to low power shutdown mode when the RS232 cable isdisconnected or the transmitters of the connected peripherals are inactive. UARTdriving the transmitter inputs is inactive for more than 30seconds and it turnon again when they sense a valid transition at any transmitter or receiverinput. AutoShutdown Plus saves power without changes to the existing BIOS oroperating system. It has a logic level output (READY) that asserts when thecharge pump is regulating and the device is ready to begin transmitting. Thistransceiver used in battery powered equipment, handheld equipment, printers,notebook, subnotebook and palmtop computers.Supply voltage range is 3V to 5.5VOperating temperature range from -40°C to 85°CREADY output is low when charge pumps are disabled in shutdown mode & high whenV- goes below -4VTwo RS232 drivers and two RS232 receiversLow dropout transmitter o/p stage enables RS232 performance from 3V-5.5V supplyw/ dual charge pumpCharge pump requires only four small 0.1µF capacitors for operation from a 3.3VsupplyApplicationsCommunications & Networking, Portable DevicesProduct InformationDevice Type: 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: -40°COperating Temperature Max: 85°CProduct Range: -Automotive Qualification Standard: -MSL: MSL 1 - UnlimitedIC Generic Number: MAX3224
