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 In enters the latches. In this condition the latches are transparent, i.e., a latch output will change state each time its I input changes. When LEn is LOW, the latches store information that was present on the I inputs a setup time preceding the HIGH-to-LOW transition on LEn. The 3- STATE outputs are controlled by the Output Enable (OEn) input. When OEn is LOW the standard outputs are in the 2- state mode. When OEn is HIGH, the standard outputs are in the high impedance mode but this does not interfere with entering new data into the latches.

The device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the Absolute Maximum Rat- ings. The “Recommended Operating Conditions” table will define the condi- tions for actual device operation. Note 3: I O Absolute Maximum Rating must be observed. Note 4: Floating or unused inputs must be held HIGH or LOW. Note 5: Outputs disabled or 3-STATE only.
