Product Summary
The SP3220EBEY device is an RS-232 driver/receiver solution intended for portable or hand-held applications such as notebook or palmtop computers. The SP3220EBEY device has a highefficiency, charge-pump power supply that requires only 0.1μF capacitors in 3.3V operation. This charge pump allows the SP3220EEA device to deliver true RS-232 performance from a single power supply ranging from +3.3V to +5.0V. The ESD tolerance of the SP3220EBEY device is over +15kV for both Human Body Model and IEC1000-4-2 Air discharge test methods. The SP3220EBEY 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.
