Note 2: All devices are 100% production tested at T
Note 3: Subscript SW refers to all SC_ and SD_ pins.
Note 4: V
Note 5: V
Note 6: All timing is measured using 20% and 80% levels, unless otherwise noted.
Note 7: Pass gate propagation delay is calculated from the 20Ω typical R
Note 8: A device must internally provide a hold time of at least 300ns for the SDA signal (referred to the V
