H = High Voltage Level; h = High Voltage Level One Setup Time Prior to the Latch Enable or Enable Low–to–High Transition; L = Low Voltage
Level; l = Low Voltage Level One Setup Time Prior to the Latch Enable or Enable Low–to–High Transition; X = Don’t Care; * = The latches are
not internally gated with the Output Enables. Therefore, data at the A or B ports may enter the latches at any time, provided that the LExx and
Exx pins are set accordingly. For ICC reasons, Do Not Float Inputs.

* Absolute maximum continuous ratings are those values beyond which damage to the device may occur. Exposure to these conditions or
conditions beyond those indicated may adversely affect device reliability. Functional operation under absolute–maximum–rated conditions is
not implied.
1. Output in HIGH or LOW State. IO absolute maximum rating must be observed.
