FACT DATA
FUNCTIONAL DESCRIPTION
The MC74AC374/74ACT374 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 the 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.
