FUNCTIONAL DESCRIPTION
The MC74AC373/74ACT373 contains eight Dtype
latches with 3state 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 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
HIGHtoLOW 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 2state
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.
