Test Conditions
Clock timing and switching characteristics are specified in accordance with minimum
operating conditions shown in the table “Recommended DC Operating Conditions” on
page 47. For all signals, AC specifications are characterized at TC = 85°C with the test
load shown in the figure to the right.
