7490 Asynchronous Decade and Binary Counter IC – DIP-14

The 7490 is a TTL logic integrated circuit designed as an asynchronous decade and binary counter. It consists of internally connected flip-flop stages arranged to provide divide-by-2 and divide-by-5 counting sections, allowing flexible configuration for mod-10 (decade) and binary counting operations. The 7490 is widely used for frequency division, event counting, timing generation, and digital clock systems. Operating on a standard 5V TTL supply, it offers reliable counting performance for digital logic and educational applications.
