Electrical Characteristics
2.1.1 Absolute Maximum Ratings
This table lists the absolute maximum ratings.
2.1.2 Power Supply Voltage Specification
This table provides the recommended operating conditions for the device. Note that the values in this table
are the recommended and tested operating conditions. Proper device operation outside of these conditions
is not guaranteed.

Notes:
1. Functional and tested operating conditions are given in Table 2. Absolute maximum ratings are stress ratings only, and
functional operation at the maximums is not guaranteed. Stresses beyond those listed may affect device reliability or cause
permanent damage to the device.
2. Caution: MV
IN
must not exceed GV
DD
by more than 0.3 V. This limit may be exceeded for a maximum of 20 ms during
power-on reset and power-down sequences.
3. Caution: OV
IN
must not exceed NV
DD
by more than 0.3 V. This limit may be exceeded for a maximum of 20 ms during
power-on reset and power-down sequences.
4. Caution: LV
IN
must not exceed LV
DD
by more than 0.3 V. This limit may be exceeded for a maximum of 20 ms during power-on
reset and power-down sequences.
