C-bus characteristics
The TEF6730AHW complies with the fast-mode I
2
C-bus protocol. The maximum I
2
C-bus
communication speed is 400 kbit/s.
SDA and SCL HIGH and LOW internal thresholds are specified according to an I
2
C-bus
voltage range from 2.5 V to 3.3 V including I
2
C-bus voltage tolerances of ±10 %. The
I
2
C-bus interface tolerates also SDA and SCL signals from a 5 V bus. Restrictions for V
IL
in a 5 V application can be derived from Table 37.
