Maxim Integrated (MAX3225ECUP+) Transceiver RS232, 3V-5.5V supply,

Product OverviewThe MAX3225ECUP+ is a ±15KV ESD protected, 1µA, 1Mbps, RS232 transceiver withAutoShutdown Plus in 20 pin TSSOP package. The device is 3V powered EIA/TIA-232and V.28/V.24 communication interfaces with automatic shutdown/wakeup feature,high data rate capabilities and enhanced electrostatic discharge (ESD)protection. The transmitter outputs and receiver inputs are protected to ±15KVusing IEC 1000-4-2 air-gap discharge, ±8KV using IEC 1000-4-2 contact dischargeand ±15KV using human body model. The device automatically enters a low powershutdown mode when the RS232 cable is disconnected or the transmitters of theconnected peripherals are inactive. The UART driving the transmitter inputs isinactive for more than 30 seconds, it turn on again when the device sense avalid transition at any transmitter or receiver input. AutoShutdown Plus savespower without changes to the existing BIOS or operating system.Two drivers and two receiversREADY output is low when charge pumps are disabled in shutdown mode & high whenV- goes below -4VSupply voltage range from 3V to 5.5VOperating temperature range from 0°C to 70°CLow dropout transmitter o/p stage enables RS232 performance from 3V-5.5V supplyw/ dual charge pumpThe charge pump requires only four small 0.1µF capacitors for operation from a3.3V supplyApplicationsCommunications & Networking, Portable DevicesProduct InformationDevice Type: TransceiverIC Interface Type: RS232No. of Drivers: 2DriversNo. of Receivers: 2ReceiversSupply Voltage Min: 3VSupply Voltage Max: 5.5VDriver Case Style: TSSOPNo. of Pins: 20PinsOperating Temperature Min: 0°COperating Temperature Max: 70°CProduct Range: -Automotive Qualification Standard: -MSL: MSL 1 - UnlimitedIC Generic Number: MAX3225
