The SP3238EEA-L is an Intelligent RS-232 Transceiver intended for portable or hand-held applications. The SP3238E 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 SP3238E device to deliver compliant RS-232 performance from a single power supply ranging from 3 to 5.5V. The SP3238E is a 5-driver/3-receiver device includes one complementary receiver that remains alert to monitor an external device"s Ring Indicate signal while the device is shutdown. 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. Otherwise, the device automatically shuts itself down drawing less than 1µA.
● Minimum 250kbps data rate under load
● Regulated charge pump yields stable RS-232 outputs regardless of VCC variations
● AUTO ON-LINE® Circuitry automatically wakes up from a 1µA shutdown
