SP3223ECY-L Datasheet

Interface - Drivers, Receivers, Transceivers


The SP3223ECY-L products are RS-232 transceiver solutions intended for portable or hand-held applications such as notebook and palmtop computers. The SP3223ECY-L/TR use an internal high-efficiency, charge-pump power supply that requires only 0.1µF capacitors in 3.3V operation. This charge pump and Sipexs driver architecture allow the SP3223E/ 3243E series to deliver compliant RS-232 performance from a single power supply ranging from +3.3V to +5.0V. The SP3223ECY-L/TR is a 2-driver/2-receiver device, and the SP3223ECY-L/TR is a 3-driver/5-receiver device ideal for laptop/notebook computer and PDA applications. The SP3243Eincludes one complementary receiver that remains alert to monitor an external devices Ring Indicate signal while the device is shutdown. The AUTO ON-LINE® feature allows the device to automatically "wake-up" during a shutdown state when an RS-232 cable is connected and a connected peripheral is turned on. Otherwise, the device automatically shuts itself down drawing less than 1µA. SP3223ECY-L 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 shutdown• Minimum 120Kbps data rate under load• Regulated Charge Pump Yields Stable RS-232 Outputs Regardless of VCC Variations• Enhanced ESD Specifications: +15KV Human Body Model +15KV IEC1000-4-2 Air Discharge +8KV IEC1000-4-2 Contact Discharge
