ABSOLUTE MAXIMUM RATINGS*

Storage Temperature

-65°C to +150°C

Voltage on Any Pin with Respect to Ground(1)

-0.5 V to +6.5 V

* Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only,

and functional operation of the device at these or any other conditions outside of those listed in the operational sections of this speciﬁcation

is not implied. Exposure to any absolute maximum rating for extended periods may affect device performance and reliability.

Note:

(1) The DC input voltage on any pin should not be lower than -0.5 V or higher than VCC + 0.5 V. During transitions, the voltage on any pin may

undershoot to no less than -1.5 V or overshoot to no more than VCC + 1.5 V, for periods of less than 20 ns. The maximum DC voltage on

address pin A0 is +10.0 V at 25°C. A series resistor of ~ 1.5 kΩ should be used when driving pin A0 to VHV, or else, the current compliance

of the VHV driver should be limited to ~ 1 mA.

(2) These parameters are tested initially and after a design or process change that affects the parameter according to appropriate AEC-Q100

and JEDEC test methods.
