SMBus/I
The physical address for the TS is binary 0 0 1 1 A2 A1 A0 RW, whereas A2, A1, and A0
are the three slave sub-address pins, and the LSB “RW” is the READ/WRITE flag.
SMBus/I
In order for this device to be both SMBus- and I

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
The SMBus minimum clock frequency is required.
The 300 ns SMBus data hold time (THD:DAT) is required (see
