Notes:
1. Unless otherwise noted, all performance specifications quoted are evaluated for worst case at both 1.4 V ≤ V_DDQ ≤ 1.6 V (i.e., 1.5 V I/O)
and 1.7 V ≤ V_DDQ ≤ 1.95 V (i.e., 1.8 V I/O) and quoted at whichever condition is worst case.
2. The power supplies need to be powered up simultaneously or in the following sequence: V_DD, V_DDQ, V_REF, followed by signal inputs. The
power down sequence must be the reverse. V_DDQ must not exceed V_DD.
3. Most speed grades and configurations of this device are offered in both Commercial and Industrial Temperature ranges. The part number
of Industrial Temperature Range versions end the character “I”. Unless otherwise noted, all performance specifications quoted are
evaluated for worst case in the temperature range marked on the device.
