Features  
Description  
• Operating Frequency Range  
The ’HC4046A and ’HCT4046A are high-speed silicon-gate  
CMOS devices that are pin compatible with the CD4046B of  
the “4000B” series. They are specified in compliance with  
- Up to 18MHz (Typ) at V

- Minimum Center Frequency of 12MHz at V

CC  
JEDEC standard number 7.  
• Choice of Three Phase Comparators  
- EXCLUSIVE-OR  
The ’HC4046A and ’HCT4046A are phase-locked-loop  
circuits that contain a linear voltage-controlled oscillator  
(VCO) and three different phase comparators (PC1, PC2 and  
PC3). A signal input and a comparator input are common to  
each comparator.  
- Edge-Triggered JK Flip-Flop  
- Edge-Triggered RS Flip-Flop  
• Excellent VCO Frequency Linearity  
The signal input can be directly coupled to large voltage  
signals, or indirectly coupled (with a series capacitor) to small  
voltage signals. A self-bias input circuit keeps small voltage  
signals within the linear region of the input amplifiers. With a  
passive low-pass filter, the 4046A forms a second-order loop  
PLL. The excellent VCO linearity is achieved by the use of  
linear op-amp techniques.  
• VCO-Inhibit Control for ON/OFF Keying and for Low  
Standby Power Consumption
