The FCT533 contains eight D-type latches with TRI-STATE standard outputs. When the Latch Enable (LE) input is HIGH, data on the D n inputs enters the latches. In this con- dition 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 tran- sition of LE. The TRI-STATE standard outputs are controlled by the Output Enable (OE) input. When OE is LOW, the stan- dard outputs are in the 2-state mode. When OE is HIGH, the standard outputs are in the high impedance mode but this does not interfere with entering new data into the latches.

The databook specifications should be met, without exception, to ensure that the system design is reliable over its power supply, temperature, and output/input loading variables. National does not recom- mend operation of FACT ® circuits outside databook specifications.
