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 0.1µF 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
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 1µA.

ABSOLUTE MAXIMUM RATINGS
These are stress ratings only and functional operation
of the device at these ratings or any other above those
indicated in the operation sections of the specifications
below is not implied. Exposure to absolute maximum
rating conditions for extended periods of time may
affect reliability and cause permanent damage to the
device.
