Exar Corporation 48720 Kato Road, Fremont CA, 94538 ? 510-668-7017 ? www.exar.com SP3220E_EB_EU_101_060311 1 SP3220E/EB/EU +3.0V to +5.5V RS-232 Driver/Receiver Pair The SP3220E devices are RS-232 driver/receiver solutions intended for portable or hand- held applications such as palmtop computers, intrumentation and consumer products. These devices incorporate a high-efficiency, charge-pump power supply that allows the SP3220E devices to deliver true RS-232 performance from a single power supply ranging from +3.0V to +5.0V. This charge pump requires only 0.1μF capacitors in 3.3V operation. The ESD toler- ance of the these devices are over +/-15kV for both Human Body Model and IEC61000-4-2 Air discharge test methods. All devices have a low-power shutdown mode where the driver outputs and charge pumps are disabled. During shutdown, the supply current falls to less than 1μA. FEATURES ■ Meets all EIA/TIA-232-F Standards from a +3.0V to +5.5V power supply ? Interoperable
