Notes
:
1. Exceeding the absolute maximum rating may damage the device.
2. The device is not guaranteed to function outside its operating rating.
3. Devices are ESD sensitive. Handling precautions recommended. Human body model, 1.5k in series with 100pF.
4. Devices participating in a transfer will timeout when any clock low exceeds the value of tTIMEOUT(min) of 25ms. Devices that have detected a timeout
condition must reset the communication no later than tTIMEOUT(max) of 35ms. The maximum value specified must be adhered to by both a master and a
slave as it incorporates the cumulative stretch limit for both a master (10ms) and a slave (25ms).
5. tHIGH(max) provides a simple guaranteed method for devices to detect bus idle conditions.
6. Rise and fall time is defined as follows: tR = VIL(max) – 0.15V to VIH(min) + 0.15V; tF = 0.9VDD to VIL(max) – 0.15V.
7. Guaranteed by design.
