BUSEN
The maximum fall time for the SDA and SCL bus lines quoted in table 5 of
output stages, 350 ns, therefore no series protection resistors may be connected between the SDA and SCL pins and the SDA and SCL
bus lines as shown in figure 36 of
SCL
SDA
In TEA5766UK, signal SDA is present on pin DATA and signal SCL on pin CLOCK.
