MC74AC563 : The MC74AC563/74ACT563 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 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 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. FUNCTION TABLE Input.
