54AC574, Octal D-Type Flip-Flop

The ’AC/’ACT574 is a high-speed, low power octal flip-flop with a buffered common Clock (CP) and a buffered common Output Enable (OE).

The information presented to the D inputs is stored in the flip-flops on the LOW-to-HIGH Clock (CP) transition.

The ’AC/’ACT574 is functionally identical to the ’AC/
