Notes
1. H = HIGH voltage level
L = LOW voltage level
X = don’t care
Z = high impedance OFF-state
NC= no change
↑ = LOW-to-HIGH CP transition
↓ = HIGH-to-LOW CP transition
Q’₆ = the information in the seventh register stage is transferred to the 8th register stage and QS_n output at the
positive clock edge
