Functional Description
The
VHC573
contains
eight
D-type
latches
with
3-STATE output buffers. When the Latch Enable (LE)
input is HIGH, data on the Dn inputs enters the latches.
In this condition the latches are transparent, i.e., a latch
output will change state each time its D input changes.
When LE is LOW the latches store the information that
was present on the D inputs, a setup time preceding the
HIGH-to-LOW transition of LE. The 3-STATE buffers are
controlled by the Output Enable (OE) input. When OE is
LOW, the buffers are enabled. When OE is HIGH the
buffers are in the high impedance mode, but, this does
not interfere with entering new data into the latches.
