  • 4 kV minimum ESD immunity
54ACTQ574 Description

    The 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.

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

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