MC74AC574/D
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.
