FUNCTIONAL DESCRIPTION
The MC74AC373/74ACT373 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 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
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.
