MC74ACT534
Octal DĆType FlipĆFlop
With 3ĆState 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.
• Edge-Triggered D-Type Inputs
• Buffered Positive Edge-Triggered Clock
• 3-State Outputs for Bus Oriented Applications
