Functional Description
The 74VCXH162373 contains sixteen edge D-type latches
with 3-STATE 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 I
n
enters the latches. In this condition the latches are
transparent, i.e., a latch output will change state each time
its I input changes. When LE
n
is LOW, the latches store
information that was present on the I inputs a setup time
preceding the HIGH-to-LOW transition on LE
n
. The 3-
STATE outputs are controlled by the Output Enable (OE
n
)
input. When OE
n
is LOW the standard outputs are in the 2-
state mode. When OE
n
is HIGH, the standard outputs are
in the high impedance mode but this does not interfere with
entering new data into the latches.
