time requirements is transferred to the Q outputs on
the positive-going edge of the clock (CLK) pulse.
Clock triggering occurs at a particular voltage level and is not related directly to the transition time of the
positive-going pulse. When CLK is at either the high or low level, the D input has no effect at the output.
