PO49FCT3805B is a 1.65V to 3.6V CMOS Dual 1 input to 5 outputs Buffered driver to achieve 800MHz output frequency. Typical applications are clock and signal distribution. Inputs can be driven from either 3.3V or 5V devices. This feature allows the use of these devices as translators in a mixed 3.3V/5V system environment.
