SP3222E - True 3.0V to 5.5V RS-232 Transceivers

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-232-F standards from a 3.0V to 5.5V power supply.
  • Minimum 120kbps data rate under full load.
  • 1μA low power shutdown with receivers active (SP3222E).
  • Interoperable with RS-232 down to a 2.7V power source.
  • Enhanced ESD specifications:.
  • ±15kV Human Body Model.
  • ±15kV IEC61000-4-2 Air Discharge.
  • ±8kV IEC61000-4-2 Contact Discharge Ordering Information - Page 21 Typical.

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.
