The "U" series is based on Sipex's SP3223E/3243E series and has been enhanced for high speed. The data rate is improved to 1000kbps, easily meeting the demands of high speed RS-232 applications. The SP3223EU and 3243EU 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 SP3223EU/3243EU series to deliver compliant RS-232 performance from a single power supply ranging from +3.0V to +5.5V. The SP3223EU is a 2-driver/2-receiver...
