Hello,

Some competitor part specifies sums of IOL and IOH. {Permissive output low current (total) = 80mA, Permissive output high current (total)= -80mA}

Could you please advice an equivalent limits ?

I found only single pin specs in the F28069 DS.

Nambu-san,
Please take a look at e2e.ti.com/.../1619432 . I am also working with our FAEs to understand your need better.

Nambu-san,

The link I pointed to is internal to TI and you probably were not able to access it. I apologize. I have extracted the gist of the response in that link and reproducing it below:

The maximum total for the device output is 20mA. This limit of 20mA will apply for total normal resistive load operation of the outputs when all are added together. In other words, the combined continuous DC current to all resistive loads of outputs on the device should not exceed 20mA. Outputs driving capacitive loads do not need to be considered in this limit.

Hareesh,
Thank you for your response.
I will talk to my customer.
