SP3222EB - True +3.0V to +5.5V RS-232 Transceiver

General Description

The SP3222EB and SP3232EB series are RS-232 transceiver solutions intended for portable or hand-held applications such as notebook or laptop computers.

The SP3222EB / SP3232EB series has a high-efficiency, charge-pump power supply that requires only 0.1µF capacitors in 3.3V operation.

Key Features

  • Meets true EIA / TIA-232-F standards from a 3.0V to 5.5V power supply.
  • 250kbps transmission rate under load.
  • 1μA low power shutdown with receivers active (SP3222EB).
  • Interoperable with RS-232 down to a 2.7V power source.

SP3222EB/SP3232EB Data Sheet True +3.0V to +5.5V RS-232 Transceivers General Description The SP3222EB and SP3232EB series are RS-232 transceiver solutions intended for portable or hand-held applications such as notebook or laptop computers. The SP3222EB / SP3232EB series has a high-efficiency, charge-pump power supply that requires only 0.1µF capacitors in 3.3V operation. This charge pump allows the SP3222EB / SP3232EB series to deliver true RS-232 performance from a single power supply ranging from 3.0V to 5.5V. The SP3222EB / SP3232EB are 2-driver / 2-receiver devices. The ESD tolerance of the SP3222EB / SP3232E devices is over ±15kV for both Human Body Model and IEC61000-4-2 Air discharge test methods.
