SP3220EEA-L/TR

The SP3220E device is an RS-232 driver/receiver solution intended for portable or hand-held applications such as notebook or palmtop computers. The SP3220E device has a high - efficiency, 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 ±15KV 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. The SP3220E device meets the EIA/TIA - 232 and V.28/V.24 communication protocols and can be implemented in battery - powered, portable, or hand - held applications such as notebook or palmtop computers. The SP3220E device 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 SP3220E device has a driver that operates at a typical data rate of 235Kbps fully loaded. The SP3220E is a 1 - driver/1 - receiver device ideal for portable or hand - held applications. The SP3220E features a 1μA shutdown mode that reduces power consumption and extends battery life in portable systems. Its receivers remain active in shutdown mode, allowing external devices such as modems to be monitored using only 1μA supply current.
