74ls90 dip IC

🔹 74LS90 Decade Counter – Divide-by-10 & Divide-by-2 Counter IC (SN74LS90N DIP-14)

The 74LS90 is a BCD decade counter and binary counter IC from the 74LS TTL logic family. It consists of four flip-flops arranged to form two separate counters—a divide-by-2 and a divide-by-5 section—which can be combined to create a divide-by-10 counter. This makes it ideal for frequency division, digital clocks, and counting applications.
