The ACQ/ACTQ573 contains eight D-type latches with
3-STATE output buffers. When the Latch Enable (LE) input is
HIGH, data on the D
n
inputs enters the latches. In this con-
dition the latches are transparent, i.e., a latch output will
change state each time its D-type input changes. When LE is
LOW the latches store the information that was present on
the D-type inputs at 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 im-
pedance mode but this does not interfere with entering new
data into the latches.

Note 1:
Absolute maximum ratings are those values beyond which damage
to the device may occur. The databook specifications should be met, without
exception, to ensure that the system design is reliable over its power supply,
temperature, and output/input loading variables. Fairchild does not recom-
mend operation of FACT
™
circuits outside databook specifications.
