Functional Description
The LVQ373 contains eight D-type latches with 3-STATE
standard outputs. When the Latch Enable (LE) input is
HIGH, data on the D
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 a setup time preceding the

HIGH-to-LOW transition of LE. The 3-STATE standard out-
puts 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.
