SP3238E

SP3238E SIGNAL PROCESSING EXCELLENCE 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 Minimum 250Kbps data rate under load 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 DESCRIPTION The SP3238E device is an RS-232 transceiver solution intended for portable or hand-held applications such as notebook and palmtop computers. The SP3238E uses 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 SP3238E device to deliver compliant RS-232 performance from a single power supply ranging from +3.0V to +5.0V. The SP3238E is a 5-driver/3-receiver device, ideal for laptop/notebook computer and PDA applications. The SP3238E includes one complementary receiver that remains alert to monitor an external device's Ring Indicate signal while the device is shutdown. The Auto-Online 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 1µ...
