SP3222E 是RS232收发器对便携式或手持式应用如笔记本或掌上型电脑的一种解决方案。SP3222E 有一个高效的电荷泵，工作电压为3.3V时只需0.1μF电容就可进行操作。电荷泵允许SP3222E 在+3.3V到+5.0V 内的某个电压下发送符合RS-232的信号。SP3222E 是一个2驱动器/2接收器的器件，适用于便携式或手持式设备（如笔记本或掌上型电脑）。SP3222E 器件的ESD保护使得驱动器和接收器的管脚可承受±15kV人体放电模式和IEC1000-4-2 气隙放电模式。SP3222E器件包含一种低功耗关断模式，该模式下器件的驱动器输出和电荷泵被禁止。关断状态下，电源电流低于1μA。
The SP3222E series is an RS-232 transceiver solution intended for portable or handheld applications such as notebook or palmtop computers. The SP3222E series has a high-efficiency, charge-pump power supply that requires only 0.1μF capacitors in 3.3V operation. This charge pump allows the SP3222E series to deliver true RS-232 performance from a single power supply ranging from +3.3V to +5.0V. The SP3222E are 2-driver/2-receiver devices. This series is ideal for portable or hand-held applications such as notebook or palmtop computers. The ESD tolerance of the SP3222E devices are over ±15kV for both Human Body Model and IEC1000-4-2 Air discharge test methods. The SP3222E device has a low-power shutdown mode where the devices' driver outputs and charge pumps are disabled. During shutdown, the supply current falls to less than 1μA.
