SP3221E

SP3221E Intelligent +3.0V to +5.5V RS-232 Transceiver ■ Meets true EIA/TIA-232-F Standards from a +3.0V to +5.5V power supply ■ Operates with EIA/TIA-232 and adheres to EIA/TIA-562 down to a +2.7V power source ■ Auto-Online™ circuitry allows 1µA supply current when in shutdown ■ 240kbps data rate under load ■ 6V/µs minimum slew rate ■ The SP3221 is the industries smallest single-supply RS-232 transceiver package ■ Enhanced ESD Specifications: +15KV Human Body Model +15KV IEC1000-4-2 Air Discharge +8KV IEC1000-4-2 Contact Discharge EN 1 16 SHUTDOWN 15 VCC 14 GND SP3221 13 12 T1OUT ONLINE C1+ 2 V+ C1C2+ C2VR1IN 3 4 5 6 7 8 11 T1IN 10 9 STATUS R1OUT Now Available in Lead Free Packaging DESCRIPTION The SP3221E is a RS-232 transceiver solution intended for portable or hand-held applications such as notebook and palmtop computers. The SP3221E has a high-efficiency, charge-pump power supply that requires only 0.1µF capacitors in 3.3V operation. This charge pump and low dropout transmitters allow the SP3221E device to deliver true RS-232 performance from a single power supply ranging from +3.3V to +5.0V. The Auto-Online feature allows the device to automatically "wake-up" during a shutdown state when an RS-232 cable is connected . Otherwise, the device automatically shuts itself down drawing less than 1µA.
