SP3222EEA-L/TR

The SP3222E and SP3232E series are RS-232 transceiver solutions intended for portable or hand-held applications such as notebook or palmtop computers. The SP3222E / SP3232E 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 / SP3232E series to deliver true RS - 232 performance from a single power supply ranging from 3.0V to 5.5V. The SP3222E / SP3232E are 2 - driver / 2 - receiver devices. The ESD tolerance of the SP3222E / SP3232E devices are over ±15KV for both Human Body Model and IEC61000 - 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.
