SP3232EH 3.3V, 460 kbps RS-232 Transceiver FEATURES Meets true EIA/TIA-232-F Standards 16 VCC C1+ 1 from a +3.0V to +5.5V power supply Interoperable with RS-232 down to a 2 GND V+ 15 +2.7V power source C1- 3 Enhanced ESD Specifications: 14 T1OUT +15kV Human Body Model SP3232EH 4 C2+ 13 R1IN +15kV IEC61000-4-2 Air Discharge +8kV IEC61000-4-2 Contact Discharge 5 12 R1OUT C2- 460kbps Minimum Transmission Rate 11 V- 6 T1IN Ideal for Handheld, Battery Operated Applications T2OUT 7 10 T2IN R2IN 8 9 R2OUT Now Available in Lead Free Packaging DESCRIPTION The SP3232EH is a 2 driver / 2 receiver RS-232 transceiver solution intended for portable or hand-held applications such as notebook or laptop computers. The data transmission rate of 460kbps can meet the demands of high speed RS-232 applications. This device has a high- efficiency, charge-pump power supply that requires only 0.1F capacitors in 3.3V operation. This charge pump allows the SP3232EH device to deliver true RS-232 performance from a single power supply ranging from +3.0V to +5.5V. The ESD tolerance of the SP3232EH device exceeds +/-15kV for both Human Body Model and IEC61000-4-2 Air discharge test methods.
