74HC4046 Overview
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 patible with standard CMOS outputs; with pullup resistors, they are patible with LSTTL outputs. The HC4046A phase–locked loop contains three phase parators, a voltage–controlled oscillator (VCO) and unity gain op–amp DEMOUT. The parators have two mon signal inputs, P IN, and SIG IN....
