Note 1: As a transmitter, the device must provide an internal minimum delay time to bridge the undefined region
(minimum 300 ns) of the falling edge of SCL to avoid unintended generation of START or STOP conditions.
Note 2: Not 100% tested. C

= total capacitance of one bus line in pF.
Note 3: The combined T

and V

specifications are due to new Schmitt trigger inputs which provide improved
noise and spike suppression. This eliminates the need for a Ti specification for standard operation.
