DESCRIPTION
The HCF4046B is a monolithic integrated circuit fabricated in Metal Oxide Semiconductor Technology, available in 16-lead dual in-line plastic or ceramic package. The HCF4046B CMOS Micropower Phase-Locked Loop (PLL) consists of a low-power, linear voltage-controlled oscillator (VCO) and two different phase comparators having a common signal-input amplifier and a common comparator input. A 5.2V zener diode is provided for supply regulation if necessary.
