Functional Description
The ACT563 contains eight D-type latches with 3-STATE
complementary outputs. When the Latch Enable (LE) input
is HIGH, data on the D
n
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 at 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 in the bi-state mode. When OE is HIGH the buffers are
in the high impedance mode but that does not interfere with
entering new data into the latches.
