74HC4046 Phase-Locked Loop

MC74HC4046A Phase-Locked Loop High Performance Silicon Gate CMOS The MC74HC4046A is similar in function to the MC14046 Metal gate CMOS device. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs. The HC4046A phase locked loop contains three phase comparators, a voltage controlled oscillator (VCO) and unity gain op amp DEMOUT. The comparators have two common signal inputs, COMP IN, and S.
