This parameter is not necessarily production tested.
VREF must be held at a valid input voltage level, and data inputs must be held LOW for a minimum time of t
taken HIGH.
VREF, data and clock inputs must be held at valid voltage levels (not floating) a minimum time of t
Includes 350 ps of test-load transmission line delay.
