SP3232E - True +3.0V to +5.5V RS-232 Transceivers

Download the SP3232E datasheet PDF. This datasheet also covers the SP3222E variant, as both devices belong to the same true +3.0v to +5.5v rs-232 transceivers family and are provided as variant models within a single manufacturer datasheet.

General Description

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 highefficiency, charge-pump power supply that requires only 0.1µF capacitors in 3.3V operation.

Key Features

  • Meets true EIA/TIA.

SP3222E / SP3232E True 3.0V to 5.5V RS-232 Transceivers Description 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 highefficiency, 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. This series is ideal for portable or hand-held applications such as notebook or palmtop computers. The ESD tolerance of the SP3222E / SP3232E devices are over ±15kV for both Human Body Model and IEC61000-4-2 Air discharge test methods.
