Functional Description
The ABT16373 contains sixteen D-type latches with 3-
STATE standard outputs. The device is byte controlled with
each byte functioning identically, but independent of the
other. Control pins can be shorted together to obtain full
16-bit operation. The following description applies to each
byte. When the Latch Enable (LE
n
) input is HIGH, data on
the D
n
enters the latches. In this condition the latches are
transparent, i.e., a latch output will change states each time
its D input changes. When LE
n
is LOW, the latches store
information that was present on the D inputs a setup time
preceding the HIGH-to-LOW transition of LE
n
. The 3-
STATE standard outputs are controlled by the Output
Enable (OE
n
) input. When OE
n
is LOW, the standard out-
puts are in the 2-state mode. When OE
n
is HIGH, the stan-
dard outputs are in the high impedance mode but this does
not interfere with entering new data into the latches.
