Functional Description
The AC/ACT373 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-type input changes.
When LE is LOW, the latches store the information that
was present on the D-type inputs a 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.
