■ Interoperable with RS-232 down to +2.7V

power source

■ 1µA Low-Power Shutdown with Receivers

Active (SP3222H)

■ Enhanced ESD Specifications:

+2kV Human Body Model

■ 460Kbps Minimum Transmission Rate

■ Ideal for Handheld, Battery Operated

Applications

DESCRIPTION

The SP3222H and the 3232H are 2 driver/2 receiver RS-232 transceiver solutions intended

for portable or hand-held applications such as notebook or palmtop computers.

Their data transmission rate of 460Kbps meeting the demands of high speed RS-232

applications. Both ICS have a high-efficiency, charge-pump power supply that requires only

0.1µF capacitors for 3.3V operation. The charge pump allows the SP3222H and the 3232H

series to deliver true RS-232 performance from a single power supply ranging from +3.3V

to +5.0V.

The SP3222H device has a low-power shutdown mode where the devices' driver outputs and

charge pumps are disabled. During shutdown, the supply current is less than 1µA.
