Information at the data (D) inputs meeting the setup 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.
