CD4566 Industrial Time-Base Generator DIP-14 (CD4566 DIP IC)
The CD4566 is a high-voltage CMOS integrated circuit designed specifically as an industrial time-base generator. It consists of a divide-by-10 ripple counter and a divide-by-5 or divide-by-6 ripple counter in a single package, making it uniquely suited for generating precise timing pulses from 50Hz or 60Hz power line frequencies.
This IC is primarily used in digital clocks, industrial timers, and frequency synthesizers where stable time-base intervals are required. It is a specialized component for Arduino electronics projects in India that involve building mains-synchronized timers or converting line frequency into 1Hz (1 pulse per second) signals for accurate timekeeping.
Key Features
- Dual independent counter stages (Divide-by-10 and Divide-by-5/6)
