SP3221E Intelligent +3.0V to +5.5V RS-232 Transceiver

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.

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 +1.
