4 2D input Data input to flip-flop 2
5 2Q tri_state Tri-state data output from flip-flop 2
6 3Q tri_state Tri-state data output from flip-flop 3
7 3D input Data input to flip-flop 3
8 4D input Data input to flip-flop 4
9 4Q tri_state Tri-state data output from flip-flop 4
10 GND power_in Ground reference
11 CLK input Clock input, positive-edge triggered
12 5Q tri_state Tri-state data output from flip-flop 5
13 5D input Data input to flip-flop 5
14 6D input Data input to flip-flop 6
15 6Q tri_state Tri-state data output from flip-flop 6
16 7Q tri_state Tri-state data output from flip-flop 7
17 7D input Data input to flip-flop 7
18 8D input Data input to flip-flop 8
19 8Q tri_state Tri-state data output from flip-flop 8
20 VCC power_in Positive power supply
