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