SP3232EEA

The SP3222E/SP3232Eseries is an RS-232 transceiver solution intended for portable or hand-held applications such as notebook or palmtop computers. The SP3222E/SP3232Eseries has a high-efficiency, charge-pump power supply that requires only 0.1µF capaci-tors in 3.3V operation. This charge pump allows the SP3222E/SP3232Eseries to deliver true RS-232 performance from a single power supply ranging from +3.0V to +5.5V. The SP3222E/SP3232Eare 2-driver/2-receiver devices. This series is ideal for portable or hand-held applications such as notebook or palmtop computers. The ESD tolerance of the SP3222E/SP3232Edevices are over +/-15kV for both Human Body Model and IEC61000-4-2 Air discharge test methods. The SP3222Edevice 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.
