Overview
The MC74HC4046ADR2G, produced by onsemi, is a high-performance silicon-gate CMOS phase-locked loop (PLL) device. It is similar in function to the MC14046 metal-gate CMOS device and is designed to be compatible with standard CMOS outputs, as well as LSTTL outputs with pullup resistors. This device integrates three phase comparators, a voltage-controlled oscillator (VCO), and a unity gain operational amplifier (op-amp) for demodulation. The MC74HC4046ADR2G is packaged in a SOIC-16 (Pb-Free) and is available in tape and reel configurations, making it suitable for various applications requiring precise phase locking and signal processing.
