74ACQ574 General Description


The ACQ/ACTQ574 is a high-speed, low-power octal D-type flip-flop with a buffered Common Clock (CP) and a buffered common Output Enable (OE). The information presented to the D inputs is stored in the flip-flops on the LOW-to-HIGH clock (CP) transition.

ACQ/ACTQ574 utilizes FACT Quiet SeriesTM technology to guarantee quiet output switching and improve dynamic threshold performance. FACT Quiet Series features GTOTM output control and undershoot corrector in addition to a split ground bus for superior performance.

The ACQ/ACTQ574 is functionally identical to the ACTQ374 but with different pin-out.
