Build Your 7490 Frequency Divider: A Powerful 2-10 Circuit
Description
This repository houses a diverse selection of frequency dividers, ranging from a division ratio of 2 to a maximum of 10. Each design utilizes the 7490 integrated circuit, which is a Decade and Binary Counter. When two instances of the 7490 are connected in series, the input frequency's division factor can be amplified, with each 7490 contributing to the overall frequency reduction. A stable +5V power supply is required for operation.
7490 Integrated Circuit
The 7490 is a versatile decade and binary counter IC manufactured by Texas Instruments. It’s a fundamental building block in digital circuit design, commonly employed in applications such as frequency dividers, digital displays, and sequential logic circuits. This IC contains a prescaler, a decade counter with up to ten steps, and a binary counter. It’s readily available, cost-effective, and well-documented, making it a popular choice for hobbyists and professional engineers alike.
