SP3222EU/SP3232EU
3.3V, 1000 kbps RS-232 Transceivers
The
SP3222EU and the SP3232EU are 2 driver, 2 receiver RS-232 transceiver solutions
intended for portable or hand-held applications such as notebook or palmtop computers.
Their data transmission rate of 1000 kbps meets the demands of high speed RS-232 ap-
plications. The
SP3222EU/SP3232EU series has a high-efficiency, charge-pump power
supply that requires only 0.1F capacitors in 3.3V operation. This charge pump allows the
SP3222EU/SP3232EU series to deliver true RS-232 performance from a single power supply
ranging from +3.0V to +5.5V. The ESD tolerance of the
SP3222EU/SP3232EU devices are
over +/-15kV for both Human Body Model and IEC61000-4-2Air discharge test methods. The
SP3222EU 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
■ Minimum 1000kbps Data Rate
■ 1A Low Power Shutdown with
Receivers active (
SP3222EU)
■ 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
■ Ideal for Handheld, Battery Operated
Applications
