The MC74AC574/74ACT574 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 MC74AC574/74ACT574 is functionally identical to the MC74AC374/ 74ACT374 except for the pinouts.
