†Notice: Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the

device. This is a stress rating only and functional operation of the device at those or any other conditions above

those indicated in the operational listings of this specification is not intended. Exposure to maximum rating

conditions for extended periods may affect device reliability.

Note 1:

Maximum limit for TJ = -40°C to +105°C based on characterization data.

Not production tested.

Typical value from bench characterization, maximum value production tested.

Input filters on the SDA and SCL inputs suppress noise spikes of less than 50 ns.
