MC74ACT563
Octal DĆType Latch
with 3ĆState Outputs
The MC74AC563/74ACT563 is a high-speed octal latch with buffered common
Latch Enable (LE) and buffered common Output Enable (OE) inputs.
The MC74AC563/74ACT563 device is functionally identical to the MC74AC573/
74ACT573, 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 MC74AC573/74ACT573 but with
Inverted Outputs
Outputs Source/Sink 24 mA
