4017 Pin Diagram. It is the output 2. Looking at the figure we see that the device is a 16 pin dil ic the pin out numbers are indicated in the diagram with their corresponding assignment names.
These are the 10 output pins on which the counting occurs they are not in order hence verify pin diagram above. Output pins q0 to q9. Connected to the ground of the circuit.
It is the output 1.
This counts with 5 d type flip flops. Decoding and control are by 16 inverters and 15 gates. It goes high when the counter reads 5 counts. This counts with 5 d type flip flops.
