The MC74AC564/74ACT564 is a high-speed, low power octal 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. The MC74AC564/74ACT564 device is functionally identical to the MC74AC574/ 74ACT574, but with inverted outputs.

• Inputs and Outputs on Opposite Sides of Package Allowing Easy Interface with Microprocessors
• Useful as Input or Output Port for Microprocessors
• Functionally Identical to MC74AC574/74ACT574 but with Inverted Outputs
• 3-State Outputs for Bus-Oriented Applications
• Outputs Source/Sink 24 mA
• ′ACT564 Has TTL Compatible Inputs
