Datasheet
DESCRIPTION
Rev. 6/25/03
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
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
