FUNCTIONAL DESCRIPTION
The MC74AC574/74ACT574 consists of eight edge-
triggered flipflops with individual Dtype inputs and
3state true outputs. The buffered clock and buffered Output
Enable are common to all flipflops. The eight flipflops
will store the state of their individual D inputs that meet the
setup and hold time requirements on the LOWtoHIGH
Clock (CP) transition. With the Output Enable (OE) LOW,
the contents of the eight flipflops are available at the
outputs. When OE is HIGH, the outputs go to the high
impedance state. Operation of the OE input does not affect
the state of the flipflops.
