... IEC1000-4-2 Air Discharge +8KV IEC1000-4-2 Contact Discharge DESCRIPTION The SP3249E device is an RS-232 transceiver solution intended for portable or hand-held applications such as notebook and palmtop computers. The SP3249E uses an internal high-efficiency, charge-pump power supply that requires only 0.1 F capacitors in 3.3V operation. This charge pump and Sipex's driver architecture allow the SP3249E device to deliver compliant RS-232 performance from a single power supply ranging from +3 ...
