Description
The SP3221E is an RS-232 transceiver solution intended for portable applications such as notebook and hand held computers. This device uses an internal high-efficiency, charge-pump power supply that requires only 0.1µF capacitors in 3.3V operation.
Key Features
- Meets true EIA/TIA-232-F Standards from a +3.0V to +5.5V power supply
- Interoperable with EIA/TIA-232 and adheres to EIA/TIA-562 down to a +2.7V power source
- AUTO ON-LINE® circuitry automatically wakes up from a 1µA typical shutdown
- Minimum 250kbps data rate under load
- Regulated charge pump yields stable RS-232 outputs regardless of VCC variations
