Note 3: All parameters are tested at T
A
= +25NC. Specifications over temperature are guaranteed by design.
Note 4: All digital inputs at V
CC
or GND.
Note 5: Guaranteed by design.
Note 6: A master device must provide a hold time of at least 300ns for the SDA signal (referred to V
IL
of the SCL signal) to bridge
the undefined region of SCL’s falling edge.
Note 7: C
