Q/D1 to Q/D8 are configured as parallel outputs.
Shift register is cleared.
First stage of S.R. becomes “L”. Other stages store the
data of previous stage, respectively.
First stage of S.R. becomes “H”. Other stages store the
data of previous stage, respectively.
The shift register remains unchanged. The Q8C output
keeps the value of the previous flip-flop.
Q/D1 to Q/D8 are configured as parallel inputs.
Q/D1 to Q/D8 are latched into the shift register.
First stage of S.R. becomes “L”. Other stages store the
data of previous stage, respectively.
First stage of S.R. becomes “H”. Other stages store the
