General Operating Conditions
Table 1. Absolute Maximum Ratings
a
a. Maximum ratings are referenced to ground (VSS). Permanent device damage is likely to occur if the ratings in this table are
exceeded. These values should not be used as the limits for normal device operations.
b. The maximum value is the lesser value of 2.5V or VDD (2.5) + 0.5 V. This specification applies to biasing the device to a steady
state for an indefinite duration.
c.
The maximum value is the lesser value of 1.7 V or VDD (2.5) + 0.5 V.
d. The maximum value must also be less than VIO.
