MC74AC573
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
