Flip Flops FAQ

What is the primary function of the master reset pin?

The master reset pin asynchronously clears all eight flip-flops to a low state regardless of the clock or data inputs.

Does this device support voltage levels below 4.5V?

No, the SN74AHCT273DGVRE4 is specified for operation between 4.5V and 5.5V; lower voltages may not meet electrical specifications.
