Please take a look at Table 6 Page 22 in the SFF 8436, where it gives
tolerances, we either need to add that couple line table in SFF8449 or change
the numbers to the minimum 1.8-5%, 2.5-5%, 3.3-5% in table 5-9..

Hello Barry,
The word MINIMUM cannot have a tolerance. For example if we have MINIMUM
voltage = 2 volts plus or minus 10 percent, the MINIMUM is really 1.8 volts.
The same is true of MAXIMUM.
Thank you,
Hugh Curley

In table 5-9 of the SFF 8449 specification it calls out a MINIMUM operating
voltage WITHOUT a tolerance, or a tolerance built into the minimum.
I was wondering if we all implied a nominal operating voltage instead in this
table and we need a tolerance, or do we need to adjust the numbers in the
table to add a tolerance? Or other such adjustment?
