Functional Description
The LVT373 and LVTH373 contain eight D-type latches
with 3-STATE standard outputs. When the Latch Enable
(LE) input is HIGH, data on the Dn 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 infor-
mation 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 out-
puts 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.
