SP3249E - Intelligent +3.0V to +5.5V RS-232 Transceiver

Description

The SP3249E device is an RS-232 transceiver solution intended for portable or hand-held applications such as notebook and palmtop computers.

The SP3249E uses an internal high-efficiency, charge-pump power supply that requires only 0.1µF capacitors in 3.3V operation.

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.
  • Minimum 250Kbps data rate under load.
  • Regulated Charge Pump Yields Stable RS-232 Outputs Regardless of VCC Variations.
  • Enhanced ESD Specifications: +15kV Human Body Model +15kV IEC61000-4-2 Air Discharge +8kV IEC61000-4-2 Contact Discharge C2+ 1 GND 2 C2- 3 V- 4 T1OUT 5 T2OUT 6 T3OUT 7 R1IN 8 R2IN 9 T4OUT 10 R3IN.
