The 74LS90 Decade Counter IC is a binary counter that counts in decimal digits, allowing for easy integration into various applications such as power amplifiers, small-signal amplifiers, operational amplifiers, and more.
By changing the modes of the Decade Counter IC, it can count up to different maximum numbers and return to zero, providing flexibility in counting operations.
Internally, the Decade Counter IC consists of four master-slave JK flip-flops connected to provide a MOD-2 (count-to-2) counter and a MOD-5 (count-to-5) counter, enhancing its counting capabilities.
A decade counter is designed to count in decimal digits, offering a user-friendly counting experience compared to binary counters. It may support various binary encodings for added versatility.
