SP3232EUCN-L Datasheet

RS-232 Interface IC


The SP3222EU and the   SP3232EUCN-L  are 2 driver, 2 receiver RS-232 transceiver solutions intended for portable or hand-held applications such as notebook or palmtop computers. Their data transmission rate of 1000 kbps meets the demands of high speed RS-232 applications. The SP3222EU/SP3232EU series has a high-efficiency,charge-pump power supply that requires only 0.1µF capacitors in 3.3V operation. This charge pump allows the SP3222EU/SP3232EU series to deliver true RS-232 performance from a single power supply ranging from +3.0V to +5.5V. The ESD tolerance of the SP3222EU/SP3232EU devices are over +/-15kV for both Human Body Model and IEC61000-4-2 Air discharge test methods. The SP3222EU device has a low-power shutdown mode where the devices driver outputs and charge pumps are disabled. During shutdown, the supply current falls to less than 1µA. SP3232EUCN-L Features • Meets true EIA/TIA-232-F Standards from a +3.0V to +5.5V power supply• Minimum 1000kbps Data Rate• 1µA Low Power Shutdown with Receivers active (SP3222EU)• Interoperable with RS-232 down to a +2.7V power source• Enhanced ESD Specifications: +15kV Human Body Model +15kV IEC61000-4-2 Air Discharge +8kV IEC61000-4-2 Contact Discharge• Ideal for Handheld, Battery Operated Applications
