SP3220EU 1Mbps速率，3.0V 到 5.5V RS-232 1-发/1-收 带低电关断
The SP3220E devices are RS-232 driver/receiver solutions intended for portable or hand-held applications such as palmtop computers, instrumentation and consumer products. These devices incorporate a high-efficiency charge-pump power supply that allows the SP3220E devices to deliver true RS-232 performance from a single power supply ranging from +3.0V to +5.0V. This charge pump requires only 0.1μF capacitors in 3.3V operation. The ESD tolerance of these devices is over ±15kV for both Human Model and IEC1000-4-2 Air discharge test methods. All devices have a low-power shutdown mode where the driver outputs and charge pumps are disabled. During shutdown, the supply current falls to less than 1μA
