74LS90 Decade Counter SMD IC
The 74LS90 is a 4-bit binary counter with a focus on decade (0-9) counting capabilities. Designed in a small SMD package, this IC contains four flip-flops and additional logic to perform both divide-by-2 and divide-by-5 counting. By cascading these sections, it counts in a sequence of ten (decade counting) and resets back to zero, making it highly useful for time division and frequency division applications. This IC is equipped with dual clock inputs: Clock A (input for the divide-by-2 section) and Clock B (input for the divide-by-5 section), allowing flexibility in cascading with other counters or in specific timing applications. It provides active low Master Reset and Master Set inputs, which allow for resetting or presetting the counter state, adding versatility in various designs.
Features:-
- High-Speed Operation
- Wide Operating Voltage Range
