Connect the circuit of Fig. 3. The count should be observed to be a count of 10, showing the BCD numbers 0 through 9. Remove the ground from pin 2, Master Reset, and connect it high. What happens? What happens if both pin 2 and pin 7 are connected high? Remove the ground from pin 2 and connect it low Explain the result.

Solution

3)Pin 2 used to rest counter. when its connected to high the output of the counter is 0000 , display 0

4)in this case the highest priority reset pin is 2, so its rest counter to 0000 and dispplay 0

5)in this case the counter perform the counting operation between 0 to 9
