AD7091R-5 and AD7415 SDA, SCL

Hi

I'm DFAE in Japan. Our customer connect AD7091R-5, AD7415 and others with I2C interface in the system. When the system is powered off, both SCL and SDA are into LOW. His end-user suspects that there is an IC in his circuit that pulls those signals LOW. Then he wants to know the equivalent circuit for SCL and SDA in the two ICs and recognize that they are not the cause. Could you please help us ? 

Regards,

Hiroyuki
