Note:
Permanent damage to the device may occur if the Absolute Maximum Ratings are exceeded. Operation should be restricted to Recommended
Operating Conditions. Exposure to conditions exceeding the Recommended Operating Conditions, for an extended period of time, may affect
reliability of this component.

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.
