The load applied to the device may permanently damage the device if it exceeds the values given in the Absolute maximum rating list (Table 4-1 、 Table 4-2 、 Table 4-3). The maximum load that can be sustained is only given here, and it does not mean that the functional operation of the device under such conditions is correct. The reliability of the device will be affected when the device works for a long time under the maximum condition.

1. When VIN>VDD, there is a forward injection current; when VIN<VSS, there is a reverse injection current. IINJ(PIN) should not exceed its maximum value. Voltage characteristics refer to Table 4-1.
2. Reverse injection current can interfere with the analog performance of the device. See section 4.3.23.
3. When the maximum current occurs, the maximum allowable voltage drop of VDD is 0.1VDD.
