SP3223EH

® SP3223EH/3243EH High Speed Intelligent +3.0V to +5.5V RS-232 Transceivers s Meets true EIA/TIA-232-F Standards from a +3.0V to +5.5V power supply s Interoperable with EIA/TIA-232 and adheres to EIA/TIA-562 down to a +2.7V power source s Auto-Online™ circuitry automatically wakes up from a 1µA shutdown s Regulated Charge Pump Yields Stable RS-232 Outputs Regardless of VCC Variations s Enhanced ESD Specifications: +15KV Human Body Model +15KV IEC1000-4-2 Air Discharge +8KV IEC1000-4-2 Contact Discharge s 460 Kbps minimum transmission rate s Ideal for High Speed RS-232 Applications DESCRIPTION The SP3223EH and 3243EH products are RS-232 transceiver solutions intended for portable or hand-held applications such as notebook and palmtop computers. The "H" series is based on Sipex's SP3223E/3243E series and has been enhanced for high speed. The data rate is improved to 460Kbps, easily meeting the demands of high speed RS-232 applications. The SP3223EH and 3243EH use an internal high-efficiency, charge-pump power supply that requires only 0.1µF capacitors in 3.3V operation. This charge pump and Sipex's driver architecture allow the SP3223EH/3243EH series to deliver compliant RS-232 performance from a single power supply ranging from +3.3V to +5.0V. The SP3223EH is a 2-driver/2-receiver device, and the SP3243EH is a 3-driver/5-receiver device, ideal for laptop/notebook computer and PDA applications. The SP3243EH includes one complementary receiver that remains alert to monitor an ...
