Hi,
I am looking for a IC that will do the following:
Count upto 10 and count down from 10, while keeping succesive pins high/low.
For example, I am picturing a chip that has an "increment" pin, when a voltage pulse is applied to the increment pin, the 1st output pin goes high, when a second pulse is applied, the 1st output pin stays high and the 2nd output pin also goes high. When the third pulse goes to the increment pin, both the 1st and 2nd out pins stay high and the 3rd outpin is high also...up to 10 output pins.
In the same manner, this chip would have a "decrement" pin, when a pulse is applied, it would reduce the number of output high pins by one. So if the count was at 3, it would reduce the count 2.
Any suggestions?
