The MC74AC573/74ACT573 is a high-speed octal latch with buffered common
Latch Enable (LE) and buffered common Output Enable (OE
) inputs.
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

FACT DATA
FUNCTIONAL DESCRIPTION
The MC74AC573/74ACT574 contains eight D-type latches with 3-state output buffers. When the Latch Enable (LE) input is HIGH, data on the Dn inputs enters the latches. In this condition the latches are transparent, i.e., a latch output will change state each time its D input changes. When LE is LOW the latches store the information that was present on the D
inputs a setup time preceding the HIGH-to-LOW transition of LE. The 3-state buffers are controlled by the Output Enable (OE
) input. When OE is LOW, the buffers are enabled. When
OE
is HIGH the buffers are in the high impedance mode but
this does not interfere with entering new data into the latches.
