SP3243EUEA-L Datasheet PDF - Exar Corporation

●The SP3243EUEA-L is a 3-driver/5-receiver Intelligent RS-232 Transceiver intended for portable or hand-held applications. The SP3243E includes one complementary receiver that remains alert to monitor an external devices ring indicate signal while the device is shutdown. The SP3243E device features slew-rate limited outputs for reduced crosstalk and EMI. The U and H series is optimized for high speed with data rates up to 1Mbps, easily meeting the demands of high speed RS-232 applications. The SP3243E series uses an internal high-efficiency, charge-pump power supply that requires only 0.1µF capacitors in 3.3V operation. This charge pump and Exar"s driver architecture allow the SP3243E series to deliver compliant RS-232 performance from a single power supply ranging from 3 to 5.5V. The AUTO ON-LINE® feature allows the device to automatically wake-up during a shutdown state when an RS-232 cable is connected and a connected peripheral is turned on.

● Minimum 1000kbps data rate

● Ideal for high speed RS-232

● AUTO ON-LINE® Circuitry automatically wakes up from a 1µA shutdown

● Regulated charge pump yields stable RS-232 outputs regardless of VCC variations
