SP3220E
SP3220E is +3.0V to +5.5V RS-232 Driver/Receiver Pair manufactured by Sipex.
Feature
- Enhanced ESD Specifications: +15k V Human Body Model +15k V IEC1000-4-2 Air Discharge +8k V IEC1000-4-2 Contact Discharge DESCRIPTION
The SP3220E device is an RS-232 driver/receiver solution intended for portable or hand-held applications such as notebook or palmtop puters. The SP3220E device has a highefficiency, charge-pump power supply that requires only 0.1µF capacitors in 3.3V operation. This charge pump allows the SP3220E device to deliver true RS-232 performance from a single power supply ranging from +3.3V to +5.0V. The ESD tolerance of the SP3220E device is over +15k V for both Human Body Model and IEC1000-4-2 Air discharge test methods. The SP3220E device has a low-power shutdown mode where the driver outputs and charge pumps are disabled. During shutdown, the supply current falls to less than 1µA.
