H = High Voltage Level; h = High Voltage Level One Setup Time
Prior to the Latch Enable High−to−Low Transition; L = Low
Voltage Level; l = Low Voltage Level One Setup Time Prior to the
Latch Enable High−to−Low Transition; NC = No Change, State
Prior to the Latch Enable High−to−Low Transition; X = High or
Low Voltage Level or Transitions are Acceptable; Z = High
Impedance State; For I_CC Reasons DO NOT FLOAT Inputs.
