NOTES:
1. Pass gate propagation delay is calculated from the 20
typical R
ON
and and the 15 pF load capacitance.
2. A device must internally provide a hold time of at least 300ns for the SDA signal (referred to the VIH
min
of the SCL signal) in order to bridge
the undefined region of the falling edge of SCL.
3. C
b
= total capacitance of one bus line in pF.
