TUSB8041: What is the difference between TUSB8041 and TUSB8041A?

Simon Chung

Part Number: TUSB8041

What is the different functionality using TUSB8041 or TUSB8041A? If my orignal circuit uses TUSB8041 to design, can I replace it with TUSB8041A? Please offer me some suggestion. Many thanks.

Greetings,

For TUSB8041A, it is recommended to use a pulldown on TEST pin. Do you have this option ?

Hi Nasser,

You mean if unused, the TEST pin should be pulled down to ground, right?

Thanks.
