Hi,

Do you confirm the mistake on the "SLLSE76M –MARCH 2011–REVISED JULY 2015* page 99 and 100 ?

On these pages, you've put the GRST# signal as output of the TUSB7340 and Input of the TPS74401.

That can't be right. The PG is open-drain and output of the TPS74401. Thus an Inout of the TUSB7340.

Hello,
Thank you for your comments, there is no mistake.
The GRST# is indeed an input that is being driven by the TPS74401.
You are probably confused by the "left pointing arrow" on the GRST# label, that does not imply the signal is going towards the TPS, it is just how the CAD software shows the labels.

Ciao Elias,

Ok. Thanks for that. It might be obvious but it disturbed me a lot.

I'll probably come with a lot more interesting questions regarding this chip....

Thank you for the job.

See you next time.
