4.0 Electrical Characteristics
V
Note 1. Minimum SCL clock frequency is limited by the bus timeout feature, which resets the serial bus interface if either SDA or SCL is held low for timeout.
Note 2. tVD:ACK = SCL LOW to SDA (out) LOW acknowledge time.
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 connected between SDA and SCL inputs and
Note 6. MSL3086/88 include input filters on SDA and SCL that suppress input noise less than 50ns
Note 7. Parameter is guaranteed by design and not production tested.
Note 8. Per JEDEC specification JESD51-5 and JESD51-12.
Note 9. Tests performed at TA = 25°C, specifications over temperature guaranteed by design.
