3V RS-232 Serial Transceiver with Logic

Selector and15kV ESD Protection

The SP3203E provides a RS-232 transceiver solution for portable and hand-held applica-

tions such as palmtops, PDA's and cell phones. The SP3203E uses an internal high-

efficiency, charge-pump that requires only 0.1µF capacitors during 3.3V operation. This

charge pump and Sipex's driver architecture allow the SP3203E to deliver compliant RS-232

performance from a single power supply ranging from +3.0V to +5.5V.

The SP3203E is a 3-driver/2-receiver device, with a unique V

and output logic levels to allow interoperation in mixed-logic voltage systems such as PDA's

and cell phones. Receiver outputs will not exceed V

are scaled by the magnitude of the V

■ 3 Driver/ 2 Receiver Architecture
