Preliminary Data Sheet
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 T
C
= 85°C with the test
load shown in the figure to the right.
