SP3220U High Speed +3.0V to +5.5V RS-232 Driver/Receiver Pair

The SP3220B/U device is an RS-232 driver/receiver solution intended for portable or hand-held applications such as notebook or palmtop computers. The SP3220B/U device has a highefficiency, charge-pump power supply that requires only 0.1µF capacitors in 3.3V operation. This charge pump allows the SP3.

SP3220U Features

* Sipex's proprietary on-board charge pump circuitry that generates 2 x VCC for RS-232 voltage levels from a single +3.0V to +5.5V power supply. This series is ideal for +3.3V-only systems, mixed +3.0V to +5.5V systems, or +5.0V-only systems that require true RS-232 performance. The SP3220B device has
