MC74AC564 Datasheet, PDF (1/8 Pages) Motorola, Inc – OCTAL D-TYPE LATCH WITH 3-STATE OUTPUTS

MC74AC564
MC74ACT564
Octal DĆType Latch
with 3ĆState Outputs
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
