DESCRIPTION

The SP3223H and 3243H products are RS-232 transceiver solutions intended for portable or

hand-held applications such as notebook and palmtop computers. The "H" series is based on

Sipex's SP3223/3243 series and has been enhanced for high speed. The data rate is

improved to 460Kbps, easily meeting the demands of high speed RS-232 applications. The

SP3223Hand3243Huseaninternalhigh-efficiency,charge-pumppowersupplythatrequires

only 0.1µF capacitors in 3.3V operation. This charge pump and Sipex's driver architecture

allow the SP3223H/3243H series to deliver compliant RS-232 performance from a single power

supply ranging from +3.3V to +5.0V. The SP3223H is a 2-driver/2-receiver device, and the

SP3243H is a 3-driver/5-receiver device, ideal for laptop/notebook computer and PDA

applications. The SP3243H includes one complementary receiver that remains alert to

monitor an external device's Ring Indicate signal while the device is shutdown.

The Auto-Online feature allows the device to automatically "wake-up" during a shutdown

statewhenanRS-232cableisconnectedandaconnectedperipheralisturnedon. Otherwise,

the device automatically shuts itself down drawing less than 1µA.
