2 1MR input Asynchronous master reset input of counter 1, active HIGH.
3 1Q0 output Flip-flop output Q0 of counter 1.
4 1CP1 input Clock input of the divide-by-5 section of counter 1, triggered on the HIGH-to-LOW transition.
5 1Q1 output Flip-flop output Q1 of counter 1.
6 1Q2 output Flip-flop output Q2 of counter 1.
7 1Q3 output Flip-flop output Q3 of counter 1.
8 GND power_in Ground (0 V).
9 2Q3 output Flip-flop output Q3 of counter 2.
10 2Q2 output Flip-flop output Q2 of counter 2.
11 2Q1 output Flip-flop output Q1 of counter 2.
12 2CP1 input Clock input of the divide-by-5 section of counter 2, triggered on the HIGH-to-LOW transition.
13 2Q0 output Flip-flop output Q0 of counter 2.
14 2MR input Asynchronous master reset input of counter 2, active HIGH.
15 2CP0 input Clock input of the divide-by-2 section of counter 2, triggered on the HIGH-to-LOW transition.
