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.

■Meets true EIA/TIA-232-F Standards from a +3.0V to +5.5V power supply

■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
