SN74LS90N IC Decade Counter 4-BIT 14DIP
The SN74LS90N is a 4-bit counter IC with a 14-pin setup. It has built-in flip-flops and circuits that allow it to count in different ways, like dividing by two or by five. This makes it useful for counting applications where you need different cycle lengths, such as dividing by ten for BCD (Binary-Coded Decimal) counting. It also has reset and set-to-nine options for more control. The SN74LS90N is a good choice for projects that need reliable counting, timing, or frequency division.
