Product Summary

The SP3222EUCY is a 2 driver, 2 receiver RS-232 transceiver intended for portable or hand-held applications such as notebook or palmtop computers. Their data transmission rate of 1000 kbps meets the demands of high speed RS-232 applications. The SP3222EUCY has a high-efficiency, charge-pump power supply that requires only 0.1uF capacitors in 3.3V operation. This charge pump allows the SP3222EU and the 3232EU to deliver true RS-232 performance from a single power supply ranging from +3.0V to +5.5V. The ESD tolerance of the SP3222EUCY are over ±15kV for both Human Body Model and IEC1000-4-2 Air discharge test methods.
