SP3243EB 智能+3.0V～+5.5V RS-232收发器
The SP3243EB products are 3 driver/5 receiver RS-232 transceiver solutions intended for portable or hand-held applications such as notebook and palmtop computers. The SP3243EB includes one complementary receiver that remains alert to monitor an external device's Ring Indicate signal while the device is shutdown. The SP3243EB and EB devices feature slew-rate limited outputs for reduced crosstalk and EMI. The "U" and "H" series are optimized for high speed with data rates up to 1Mbps, easily meeting the demands of high speed RS-232 applications. The SP3243EB 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 SP3243EB series to deliver compliant RS-232 performance from a single power supply ranging from +3.0V 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 con- nected and a connected peripheral is turned on. Otherwise, the device automatically shuts itself down drawing less than 1μA.
