Maxim Integrated (MAX3243CAI+T) Transceiver RS232

Product OverviewThe MAX3243CAI+T is a 3V to 5.5V RS232 transceiver with AutoShutdown in 28 pinSSOP package. Whenever the device does not sense a valid signal level on thereceiver inputs, the onboard power supply and driver turns to shut down. Thisoccurs if the RS232 cable is disconnected or if the transmitters of theconnected peripheral are turned off. The system turns on again when a validlevel is applied to any RS232 receiver input. It requires only 0.1µF capacitorsin 3.3V operation. The high efficiency, dual charge pump power supply and a lowdropout transmitter combine to deliver true RS232 performance from a single +3Vto +5.5V supply.Three drivers & five receivers with a complementary always-active receiver forexternal monitoringOperating temperature range from 0°C to 70°CAutoShutdown feature enabled after no activity on receiver input for 30µsSupply current is 1µA in shutdown modeSoftware control option for shutdownIntegrated charge pump circuitry eliminates need of ±12 supply & operates insingle 3.3V/5V supplyApplicationsCommunications & Networking, Industrial, Portable DevicesProduct InformationDevice Type: TransceiverIC Interface Type: RS232No. of Drivers: 3DriversNo. of Receivers: 5ReceiversSupply Voltage Min: 3VSupply Voltage Max: 5.5VDriver Case Style: SSOPNo. of Pins: 28PinsOperating Temperature Min: 0°COperating Temperature Max: 70°CProduct Range: -Automotive Qualification Standard: -MSL: MSL 1 - Unlimited
