No, create an account now. Jul 17, 22, 1, The count-down terminal is held high. I haven’t tested this, but it should work. You won’t need the inverter in the clock line if your clock doesn’t go anywhere else. Both borrow and carry outputs are available to cascade both the up and daasheet counting functions. Dec 1, 74ls193 datasheet The counter chip I had 74ls193 datasheet hand 74sl193 aand I’ve spend a lot of time reading up on it and trying to make it work, but for the life of me I can’t get the thing to count.

I read your post about cascading them together.

A clear input has been provided which, when taken to a high 74ls193 datasheet, forces all outputs to the low level; independent of the count and load inputs. Welcome to our site!

I didn’t know what to do with daatasheet inputs or whether to take the outputs into the inputs of the next chip. When I flip the switch I know I’m getting a slow pulse maybe that’s 74ls193 datasheet problem, and if so, is there 74ls193 datasheet circuit I can build to make a quick single pulse?
