■ Palmtops

■ Cell phone Data Cables

■ PDA's

DESCRIPTION

The SP3203 provides a RS-232 transceiver solution for portable and hand-held applications

such as palmtops, PDA's and cell phones. The SP3203 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 SP3203 to deliver compliant RS-232 performance

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

The SP3203 is a 3-driver/2-receiver device, with a unique V_Lpin to program the TTL input

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_Lfor V_OHand transmitter input logic levels

are scaled by the magnitude of the V_Linput.
