SP3223E数据手册集成电路（IC）的驱动器接收器收发器规格书PDF

描述 Description

The SP3223 products are RS-232 transceiver solutions intended for portable applications such as notebook and hand held computers. These products use an internal high-efficiency, charge-pump power supply that requires only 0.1μF capacitors in 3.3V operation. This charge pump and Exar's driver architecture allow the SP3223 series to deliver compliant RS-232 performance from a single power supply ranging from +3.3V to +5.0V. The SP3223 is a 2-driver/2-receiver device ideal for laptop/notebook computer and PDA applications.
The AUTO ON-LINE® feature allows the device to automatically \"wake-up\" during a shutdown state when an RS-232 cable is connected and a connected peripheral is turned on. Otherwise, the device automatically shuts itself down drawing less than 1μA.
