Functional Description
The 74AC573 and 74ACT573 contain eight D-type latches
with 3-STATE output buffers. When the Latch Enable (LE)
input is HIGH, data on the D
this condition the latches are transparent, i.e., a latch out-
put will change state each time its D-type input changes.
When LE is LOW the latches store the information that was

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 buff-
ers are in the high impedance mode but this does not inter-
fere with entering new data into the latches.
