Functional Description
The LVQ573 contains eight D-type latches with 3-STATE
output buffers. When the Latch Enable (LE) input is HIGH,
data on the D
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 buffers are controlled by the
Output Enable (OE) input. When OE is LOW, the buffers
are enabled. When OE is HIGH the buffers are in the high
impedance mode but this does not interfere with entering
new data into the latches.
