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.

■ 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
