74HC4046 Description
SL74HC4046 Phase-Locked Loop High-Performance Silicon-Gate CMOS The device inputs are patible with standard CMOS outputs; with pullup resistors, they are patible with LS/ALSTTL outputs. The SL74HC4046 phase-locked loop contains three phase parators, a voltage-controlled oscillator (VCO) and unity gain opamp DEM OUT.
