MC74ACT573
Octal DĆType Latch
with 3ĆState Outputs
The MC74AC573/74ACT573 is a high-speed octal latch with buffered common
Latch Enable (LE) and buffered common Output Enable (OE) inputs.
The MC74AC573/74ACT573 is functionally identical to the MC74AC373/
74ACT373 but has inputs and outputs on opposite sides.
• Inputs and Outputs on Opposite Sides of Package
Allowing Easy Interface with Microprocessors
• Useful as Input or Output Port for Microprocessors
• Functionally Identical to MC74AC373/74ACT373
• 3-State Outputs for Bus Interfacing
• Outputs Source/Sink 24 mA
• ′ACT573 Has TTL Compatible Inputs
