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 DESCRIPTION SELECTION TABLE Now Available in Lead Free Packaging V- 1 2 3 4 13 14 15 16 5 6 7 12 11 10 C1+ V+ C1- C2+ C2- R1IN GND VCC T1OUT No Connect 8 9 SP3220 E/EB/EU T1IN No Connect R1OUT EN SHDN MODEL Power Supplies RS-232 Drivers RS-232 Receivers External Components Shutdown Data Rate SP3220E +3.0V to +5.5V 1 1 4 Capacitors Yes 120kbps SP3220EB +3.0V to +5.5V 1 1 4 Capacitors Yes 250kbps SP3220EU +3.0V to +5.5V 1 1 4 Capacitors Yes 1Mbps |
