description/ordering information

These circuits are positive-edge-triggered D-type

flip-flops with a direct clear (CLR

) input.

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 directly related

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.
