MC74AC534 MC74ACT534 Octal DType FlipFlop With 3State Outputs The MC74AC534/74ACT534 is a high-speed, low-power octal D-type flip-flop featuring separate D-type inputs for each flip-flop and 3-state outputs for bus oriented applications. A buffered Clock (CP) and Output Enable (OE) are common to all flip flops. The ′AC/ACT534 is the same as the ′AC/ACT374 except that the outputs are inverted.

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 inputs that meet the setup and hold times 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. W……
