Functional Description
The 74VCX16841 contains twenty 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 20-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 trans-
parent, i.e., a latch output will change states each time its
D-type input changes. When LE
n
is LOW, the latches store
information that was present on the D-type 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.
