3 Description
These devices 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.
