Note 4: The parameters are guaranteed by design. The limits are based on statistical analysis of the device performance over PVT (process, voltage and
temperature) range.
Note 5: T
SET
and T
HOLD
time specify that data must be in a stable state before and after the SEL transition.
Note 6: The parameters are guaranteed by design. The limits are based on statistical analysis of the device performance over PVT range with the following
equipment test setup: HP70004A (display mainframe) with HP70841B (pattern generator), 5 feet of RG-142 cable with DUT test board and HP83480A (digital scope
mainframe) with HP83483A (20GHz scope module).
