CD4046 Micropower Phase-locked Loop
Package SOIC Series CD4000 (CMOS)
CD4046 overview
CD4046 belongs to the 4000 Series CMOS Logic Family of Integrated Circuits (IC's) constructed with N- and P-channel enhancement mode transistors. CD4046 has Micropower Phase-locked Loop
CD4046 has a supply voltage range of 5V to 20V, which is much higher than any contemporary logic family. It has buffered output which improves transfer characteristics by providing very high gain. All inputs are protected against static discharge with diodes to VDD and VSS.
