Note 3. t
Note 4. A master device must internally provide an SDA hold time of at least 300ns to ensure an SCL low state.
Note 5. The maximum SDA and SCL rise times is 300ns. The maximum SDA fall time is 250ns. This allows series protection resistors to be
Note 6. MSL2041/2 includes input filters on SDA and SCL that suppress noise less than 50ns.
Note 7. Parameter is guaranteed by design and not production tested.
