H = High Voltage Level; h = High Voltage Level One Setup Time Prior to the Low–to–High Clock Transition; L = Low Voltage Level; l =

Low Voltage Level One Setup Time Prior to the Low–to–High Clock Transition; NC = No Change; X = High or Low Voltage Level and

Transitions are Acceptable; Z = High Impedance State; ↑ = Low–to–High Transition; ↑ = Not a Low–to–High Transition; For ICC Reasons

DO NOT FLOAT Inputs
