What the SP3222E does
The SP3222E/SP3232E series are true RS-232 transceivers designed for portable and hand-held applications like notebook computers. These 2-driver/2-receiver devices operate from a single 3.0V to 5.5V power supply using an efficient charge pump. They support a maximum data rate of 120kbps under full load and feature enhanced ESD tolerance of ±15kV for human body models. The parts include a low-power shutdown mode that reduces supply current to less than 1µA. Available in SSOP, SOIC, TSSOP, and PDIP packages, they meet EIA/TIA-232-F standards and are ideal for interfacing logic levels with RS-232 signals in battery-powered systems.
