DESCRIPTION

The SP3222EH and the 3232EH 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 SP3222EH and the 3232EH series to deliver true RS-232 performance from a single power supply ranging from +3.3V to +5.0V. The ESD tolerance of the SP3222EH/3232EH devices exceeds +15kV for both Human Body Model and IEC1000-4-2 Air discharge test methods.
