DESCRIPTION

The

SP3223E

and

3243E

products are RS-232 transceiver solutions intended for portable or

hand-held applications such as notebook and palmtop computers. The

SP3223E

and

3243E

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

SP3223E/

3243E

series to deliver compliant RS-232 performance from a single power supply ranging

from +3.3V to +5.0V. The

SP3223E

is a 2-driver/2-receiver device, and the

SP3243E

is a

3-driver/5-receiver device ideal for laptop/notebook computer and PDA applications.

The

SP3243E

includes one complementary receiver that remains alert to monitor an external

device's Ring Indicate signal while the device is shutdown.

The AUTO ON-LINE

廬

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).
