MC74ACT564 Octal DType FlipFlop with 3State Outputs The MC74ACT564 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 MC74ACT564 device is functionally indentical to the MC74ACT574, but with inverted outputs.
