I²C SWITCHING CHARACTERISTICS
Note 1. All parameters are tested at T
Note 2. Minimum SCL clock frequency is limited by the bus timeout feature, which resets the serial bus interface if either SDA
Note 3. t
Note 4. t
Note 5. A master device must internally provide an SDA hold time of at least 300ns to ensure an SCL low state
Note 6. The maximum SDA and SCL rise times are 300ns. The maximum SDA fall time is 250ns. This allows series protection resistors to be
Note 7. MSL3162 includes input filters on SDA, SCL, AD0, and AD1 inputs that suppress noise less than 50ns
Note 8. Subject to thermal dissipation characteristics of the device
Note 9. When mounted according to JEDEC, JEP149, and JESD51-12 for a two-layer PCB, θ
Note 10. Guaranteed by design and characterization. Not production tested
