Need Ic which can Enable Its outputs One by One!


Recommended Posts

I need an IC (i.e. 74XXX Series) with 8 or more outputs. The outputs will be enabled on by on after each other when I trigger the Clock pulse Input. the important note is that the outputs should stay enabled until I reset the IC.

I never heard of a 74XX that would do that exact thing. However, I did design a circuit that accomplishes the same thing. You could drive it with something like a ring counter (4071) or use a binary counter driving the address lines of a 3-line-to-eight-line decoder. Once you run that, you will have eight lines that go high in succession, and stay high until you reset.

This works since I have built it.
