Functional Description
The LVX573 contains eight D-type latches. When the
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 informa-
tion that was present on the D inputs a setup time preced-
ing 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.
