MC74HC4046A - 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, COMPIN, and S
