Overview
The 74AHCT574PW,112, produced by Nexperia USA Inc., is an 8-bit positive-edge triggered D-type flip-flop with 3-state outputs. This device is part of the 74AHCT family, which is known for its compatibility with TTL (Transistor-Transistor Logic) input levels. The flip-flop stores the state of its individual D-inputs that meet the set-up and hold time requirements on the LOW-to-HIGH clock (CP) transition. It features a clock (CP) and output enable (OE) inputs, where a HIGH on OE causes the outputs to assume a high-impedance OFF-state without affecting the state of the flip-flops.
