SP3243EBEA-L/TR

接口集成电路 3 Driver/5 Receiver Intelligent +3.0V to +5.5V RS-232 Transceivers

DESCRIPTION SP3243EBEA-L/TR

The SP3243EBEA-L/TR SP3243E products are 3 driver/5 receiver RS-232 transceiver solutions intended for portable  or hand-held applications such as notebook and palmtop computers. The SP3243E includes one  complementary receiver that remains alert to monitor an external device's Ring Indicate signal while  the device is shutdown. The SP3243E 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 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 +3.0V 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 connected  and a connected peripheral is turned on. Otherwise, the device automatically shuts itself down  drawing less than 1μA.
