SP3220E/EB/EU
+3.0V to +5.5V RS-232 Driver/Receiver Pair
The
SP3220EdevicesareRS-232driver/receiversolutionsintendedforportableorhand-held
applications such as palmtop computers, instrumentation and consumer products. These
devices incorporate a high-efficiency, charge-pump power supply that allows the
SP3220E
devices to deliver true RS-232 performance from a single power supply ranging from +3.0V
to +5.0V. This charge pump requires only 0.1µF capacitors in 3.3V operation. The ESD toler-
ance of the these devices are over +/-15kV for both Human Body Model and IEC61000-4-2
Air discharge test methods. All devices have a low-power shutdown mode where the driver
outputs and charge pumps are disabled. During shutdown, the supply current falls to less
than 1µA.
FEATURES
■ Meets all EIA/TIA-232-F Standards
from a +3.0V to +5.5V power supply
• Interoperable with RS-232 and V.28 at +2.7V
■ Supports High Serial Data Rates:
• 120kbps SP3220E
• 250kbps SP3220EB
• 1Mbps SP3220EU
■ 1µA Low Power Shutdown Mode
■ Footprint Compatible with MAX3221E, ISL3221
■ 4 x 1.0µF External Charge Pump Capacitors
■ Improved ESD Specifications:
+15kV Human Body Model
+15kV IEC61000-4-2 Air Discharge
+8kV IEC61000-4-2 Contact Discharge
