MC74AC574, MC74ACT574 Octal D FlipFlop with 3State Outputs The MC74AC574/74ACT574 is a highspeed, low power octal flipflop with a buffered common Clock (CP) and a buffered common Output Enable (OE). The information presented to the D inputs is stored in the flipflops on the LOWtoHIGH Clock (CP) transition. The MC74AC574/74ACT574 is functionally identical to the MC74AC374/74ACT374 except for the pinouts.
