*
= When the input is High, all I/O terminals are at the high impedance state, sequential operation or clearing of the register is not
affected.
H
= High voltage level
L
= Low voltage level
NC = No change
X
= Don’t care
Z
= High impedance “off” state
↑
= Low-to-High clock transition
I0–I7 = The level of the steady state input at the respective I/O terminal is loaded into the flip-flop while the flip-flop outputs (except Q7) are
isolated from the I/O terminal.
D0–D7 = The level of the steady state inputs to the serial multiplexer input.
O0–O7 = The level of the respective Qn flip-flop prior to the last clock Low-to-High transition.
↑
= Not a Low-to-High clock transition
