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
(0
–
8)
or BI
(0
–
8)
) enters the latches. In this condition the
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
the inputs a set-up time preceding the HIGH-to-LOW tran-
sition of the Latch Enable. The 3-STATE standard outputs
are controlled by the Output Enable (AOE
1
or BOE
1
) input.
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.
