SP3223E 概述

The SP3223E products are RS-232 transceiver solutions intended for portable applications such as notebook and hand held computers. The SP3223E use an internal high-efficiency, charge-pump power supply that requires only 0.1μF capacitors in 3.3V operation. This charge pump and Sipex's driver architecture allow the SP3223E series to deliver compliant RS-232 performance from a single power supply ranging from +3.3V to +5.0V. The SP3223E is a 2- driver/2-receiver device ideal for laptop/notebook computer and PDA applications.
