4040 IC 12-Stage Binary Ripple Counter CMOS
The CD4040BE is a high-speed CMOS integrated circuit that functions as a 12-stage binary ripple counter. Designed to deliver excellent performance in digital systems, this IC is commonly used in applications requiring binary division of frequency signals or counting events. It offers asynchronous reset capabilities, ensuring it can be reset at any time regardless of the clock signal. With low power consumption and high noise immunity, it is suitable for both hobbyist and industrial-level electronic circuit designs.
The CD4040BE provides twelve flip-flop stages connected in a ripple configuration, meaning each output stage triggers the next. This configuration allows the IC to divide the input frequency by 2^n, where n is the stage number. It works well with a wide voltage range (typically from 3V to 15V), making it compatible with a broad spectrum of logic levels. Its compact 16-pin DIP package simplifies integration into breadboards and PCBs, ensuring hassle-free development.
