SP3222EB/SP3232EB
True +3.0V to +5.5V RS-232 Transceivers
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 0.1F 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 1A.
FEATURES
■ Meets true EIA/TIA-232-F Standards
from a +3.0V to +5.5V power supply
■ 250kbps Transmission Rate Under Load
■ 1A 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
