1 / 20 page Exar Corporation 48720 Kato Road, Fremont CA, 94538 • 510-668-7017 • www.exar.com SP3222EU/SP3232EU_102_031413 1 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 0.1µF 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 1µA. FEATURES ■ Meets true EIA/TIA-232-F Standards from a +3.0V to +5.5V power supply ■ Minimum 1000kbps Data Rate ■ 1µA 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 DESCRIPTION SELECTION TABLE Now Available in Lead Free Packaging V- 1 2 3 4 15 16 17 18 5 6 7 14 13 12 SHDN C1+ V+ C1- C2+ C2- EN R1IN GND VCC T1OUT 8 9 10 11 R2IN SP3222EU T2OUT T2IN T1IN R1OUT nSOIC R2OUT MODEL Power Supplies RS-232 Drivers RS-232 Receivers External Components Shutdown TTL 3-State # of Pins SP3222EU +3.0V to +5.5V 2 2 4 Capacitors Yes Yes 18, 20 SP3232EU +3.0V to +5.5V 2 2 4 Capacitors No No 16 |
