DESCRIPTION

The 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 con-

nected and a connected peripheral is turned on. Otherwise, the device automatically shuts itself down

drawing less than 1µA.
