I read the datasheet. But i am not understanding it.

Here, the pulser is a clock source: Is this a homework assignment? Sep 22, 3. Nov 12, 1, As SgtWookie asked, is this a homework assignment?

Do you have to use this particular IC or can you use another? This means it will count fromnot Therefore, you’re going to see some interesting things on the display from 10 to 15 – see the datasheet for the 74LS47, it will show you. If you only want to count from datashfet to 9 and not 0 – 15, then you need a decade counter, not a binary counter. Take another look at the 74LS datasheet, it should also list another IC – one with a decade counter.
