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

SP3223H

and

3243H

use an internal high-efficiency, charge-pump power supply that requires

only 0.1碌F 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

state when an RS-232 cable is connected and a connected peripheral is turned on. Otherwise,

the device automatically shuts itself down drawing less than 1碌A(chǔ).
