H = High Voltage Level; L = Low Voltage Level; X = Don’t Care; ↑ = Low–to–High Clock Transition; ↑ = NOT Low–to–High Clock Transition; NC = No Change; * = The

clocks are not internally gated with either the Output Enables or the Source Inputs. Therefore, data at the A or B ports may be clocked into the storage registers, at any

time. For ICC reasons, Do Not Float Inputs.
