Notes: 1. Except for the rating ”Operating Temperature Range”, stresses above those listed in the Table ”Absolute Maximum Ratings”

may cause permanent damage to the device. These are stress ratings only and operation of the device at these or any other

conditions above those indicated in the Operating sections of this specification is not i mplied. Exposure to Absolute Maximum

Rating conditions for extended periods may affect device reliability. Refer also to the STMicroelectronics SURE Program and other

relevant quality documents.

2. Minimum DC voltage on Input or Output is –0.5V with possible undershoot to –2.0V for a period less than 20ns. Maximum DC

3. Depends on range.
