FAQ

What is the trigger type for the 74LVC273D?

The device uses positive-edge triggering, transferring data from the D input to the Q output on the LOW-to-HIGH transition of the clock pulse.

Does the 74LVC273D have asynchronous control inputs?

No, the standard 74LVC273 does not include asynchronous set or reset inputs; it relies on the master reset function for initialization.
