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.
