The SP3222EB/3232EB is an RS-232 transceiver solution from Sipex Corporation that supports power supplies from +3.0V to +5.5V, a transmission rate of up to 250kbps, and a low-power shutdown mode with a current consumption of 1µA. It has also passed the ±15kV Human Body Model, ±15kV IEC1000-4-2 Air Discharge, and ±8kV IEC1000-4-2 Contact Discharge tests.
The SP3222EB/3232EB series are RS‑232 transceiver solutions intended for portable or hand‑held applications such as notebook and palmtop computers. They operate from a single +3.0 V to +5.5 V supply and feature a charge‑pump architecture that provides true RS‑232 voltage levels while consuming low power.
The datasheet provides absolute maximum ratings, electrical specifications, typical performance curves, pin‑out tables, and ordering information for multiple package types. It also includes theory of operation, shutdown mode behavior, and ESD protection details.
