SP3222EB/SP3232EB
True +3.0V to +5.5V RS-232 Transceivers
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
■ Enhanced ESD Specifications:
+15kV Human Body Model
+15kV IEC61000-4-2 Air Discharge
+8kV IEC61000-4-2 Contact Discharge
DESCRIPTION
The SP3222EB/SP3232EB series is an RS-232 transceiver solution 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/SP3232EB
devices is over +/-15kV for both Human Body Model and IEC61000-4-2 Air discharge test
methods. The SP3222EB 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.

ABSOLUTE MAXIMUM RATINGS
These are stress ratings only and functional operation
of the device at these ratings or any other above those
indicated in the operation sections of the
specifications
below is not implied. Exposure to absolute maximum
rating conditions for extended periods of time may
affect reliability and cause permanent damage to the
device.
