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 the clock-enable input () 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 inputs are at either the high or low level, the data (D) input signal has no effect at the output. The circuits are designed to prevent false clocking by transitions at the clock-enable () input.

The 74ACT11378 is characterized for operation from - 40°C to 85°C.
