General Specifications

Operating Conditions

Stresses beyond those listed in Table 3-1 may cause permanent damage to the device.

Exposure to absolute maximum rated conditions for extended periods may affect device reliability.

Devices should not be operated outside the recommended operating ranges specified in Table 3-2

on page 3-3.

Notes:

1. The device should be operated within the limits specified by the datasheet. During transitions, the input

signal may undershoot or overshoot according to the limits shown in Table 3-4 on page 3-4.

2. Analog data not valid beyond 3.65 V.

3. For flash programming and retention maximum limits, refer to Table 3-5 on page 3-5. For recommended

operating limits refer to Table 3-2 on page 3-3.
