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 Series™ technology to guarantee quiet output switching and improve dynamic threshold performance. FACT Quiet Series fea- tures GTO™ 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. Ordering Information Device also available in Tape and Reel. Specify by appending suffix “X” to the ordering number.
