FACT DATA
FUNCTIONAL DESCRIPTION
The MC74AC574/74ACT574 consists of eight edge-
triggered flip-flops with individual D-type inputs and 3-state
true outputs. The buffered clock and buffered Output Enable
are common to all flip-flops. The eight flip-flops will store the
state of their individual D inputs that meet the setup and hold
time requirements on the LOW-to-HIGH Clock (CP) transition.
With the Output Enable (OE) LOW, the contents of the eight
flip-flops 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 flip-flops.
