MAXIMUM RATING

Stressing the device above the rating listed in the

Absolute Maximum Ratings table may cause per-

manent damage to the device. Exposure to Abso-

lute Maximum Rating conditions for extended

periods may affect device reliability. These are

stress ratings only and operation of the device at

these or any other conditions above those indicat-

ed in the Operating sections of this specification is

not implied. Refer also to the STMicroelectronics

SURE Program and other relevant quality docu-

ments.

Table 8. Absolute Maximum Ratings

Note: 1. Compliant with the ECOPACK® 7191395 specification for Lead-free soldering processes.

2. Not exceeding 250°C for more than 30s, and peaking at 260°C.

3. Minimum voltage may undershoot to –2V during transition and for less than 20ns during transitions.

4. Maximum voltage may overshoot to VCC +2V during transition and for less than 20ns during transitions.

5. VPP must not remain at 12V for more than a total of 80hrs.
