2 / 6 page Functional Description The ’ACTQ16373 contains sixteen D-type latches with TRI-STATE standard 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 D n enters the latches. In this condition the latches are transparent, i.e., a latch output will change states each time its D input changes. When LE n is LOW, the latches store in- formation that was present on the D inputs a setup time pre- ceding the HIGH-to-LOW transition of LE n. The TRI-STATE standard 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.
