The SP3222E/3232E series is an RS-232 transceiver solution intended for portable or handheld applications such as notebook or palmtop computers. The SP3222E/3232E series has a high-efficiency, charge-pump power supply that requires only 0.1µF capacitors in 3.3V operation. This charge pump allows the SP3222E/3232E series to deliver true RS-232 performance fro.
of the SP3222E/3232E devices are over ±15kV for both Human Body Model and IEC1000-4-2 Air discharge test methods. The SP3222E device has a low-power shutdown mode where the devices' driver outputs and charge pumps are disabled. During shutdown, the supply current falls to less than 1µA.
