description/ordering information
These positive-edge-triggered D-type flip-flops
have a direct clear (CLR) input.
Information at the data (D) inputs meeting the
setup time requirements is transferred to the
outputs on the positive-going edge of the clock
(CLK) pulse. Clock triggering occurs at a
particular voltage level and is not directly related
to the transition time of the positive-going edge of
CLK. When CLK is at either the high or low level,
the D input has no effect at the output.
