Functional Description
The ACQ/ACTQ574 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-type 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.
