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 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 input.

The 74ACT11377 is characterized for operation from - 40°C to 85°C.
