5.5 V steady state voltage tolerance on inputs and outputs is valid only when the supply voltage is present. 3.8 V steady state voltage
tolerance on inputs and outputs when no supply voltage is present.

A detailed description of the I

C-bus specification, with applications, is given in brochure “The I

C-bus and how to use it” This brochure
may be ordered using the code 9398 393 40011.
[2]
Minimum SCL clock frequency is limited by the bus time-out feature, which resets the serial bus interface if SDA is held LOW for a
minimum of 25 ms.
