In order for this device to be both SMBus- and I
each specification. The requirements which enable this device to co-exist with devices on
either an SMBus or an I

Since the voltage levels are specified only within 3.3 V ±10%, there are no compatibility
concerns with the SMBus/I
Figure 7.
The SMBus minimum clock frequency is required.
The 300 ns SMBus data hold time (THD:DAT) is required (see
page
The SMBus time-out is maximum 40 ms (temperature sensor only).
