Functional Description
The ACQ/ACTQ373 contains eight D-type latches with 3-
STATE standard outputs. When the Latch Enable (LE)
input is HIGH, data on the D
n
inputs enters the latches. In
this condition the latches are transparent, i.e., a latch out-
put 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 at setup time preceding the HIGH-
to-LOW transition of LE. The 3-STATE standard outputs
are controlled by the Output Enable (OE) input. When OE
is LOW, the standard outputs are in the 2-state mode.
When OE is HIGH, the standard outputs are in the high
impedance mode but this does not interfere with entering
new data into the latches.
