SP3220 - Sipex

SP3220 +3.0V to +5.5V RS-232 Driver/Receiver Pair

The SP3220 device is an RS-232 driver/receiver solution intended for portable or hand-held applications such as notebook or palmtop computers. The SP3220 device has a highefficiency, charge-pump power supply that requires only 0.1µF capacitors in 3.3V operation. This charge pump allows the SP3220 device to deliver true RS-232 performance from a single power .

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 SP3220 device has a driver that operates at a typical data rate of 235Kbps fully loaded. The SP3220 is a 1-driver/1-receiver device ideal for portable or hand-held applications. The SP3220 features a 1µA shutdown mode that reduces power consumption and extends battery life in portable systems. Its receivers remain ac.
