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