Functional Description
The SCAN18373T consists of two sets of nine D-type
latches with 3-STATE standard outputs. When the Latch
Enable (ALE or BLE) input is HIGH, data on the inputs
(AI
latches are transparent, i.e., a latch output will change
state each time its input changes. When Latch Enable is
LOW, the latches store the information that was present on

When Output Enable is LOW, the standard outputs are in
the 2-state mode. When Output Enable is HIGH, the stan-
dard outputs are in the high impedance mode, but this
does not interfere with entering new data into the latches.
