description
These circuits are positive-edge-triggered D-type flip-flops with a clock-enable input.
Information at the D inputs meeting the setup time requirements is transferred to the Q outputs on the
positive-going edge of the clock pulse if CLKEN is low. Clock triggering occurs at a particular voltage level and
is not directly related to the transition time of the positive-going pulse. When the clock input is at either the high
or low level, the D input signal has no effect at the output. The circuits are designed to prevent false clocking
by transitions at the CLKEN input.
The 74ACT11379 is characterized for operation from − 40°C to 85°C.
