Hi Team,
Our customer would like to know the absolute Maximum Ratings of SDA_SRC and SCL_SRC.
They are evaluating the output short test of power supply 5V for TMDS171.
(Please refer to the following image.)
If 5V line is shorted, SDA_SRC and SCL_SRC pins are “-0.4V during around 40ns”.
We understand that “-0.4V” exceeds -0.3V(absolute Maximum Ratings) but this voltage is only around 40ns period(so it is short time).
Does TMDS171 fail by this voltage?
Unfortunately, I can’t see the internal circut of ACTIVE DDC BLOCK but guess that TMDS171 doesn’t fail.
Is my understanding correct?
If you contact to below my e-mail address or let me know your e-mail address,
I can send the customer information.
I’m looking forward to hearing from you.

Regards,
Kanemaru
