TXU0304: TXU0304DTRR Performance problem

yingjiao LI

Part Number: TXU0304

This model is used at a temperature of 25° and a voltage of 3.3V. The chip output is abnormal and the failure ratio is 30%.

Could you please help confirm the cause

Thank you.

I am not able to read the details on that screen. (Please note that your oscilloscope has a built-in screenshot function.)

But this looks as if some other device also drives the output. If there is no other output connected to the line, check for shorts.

Hi Yingjiao,

Please note that the feedback still holds i.e is this abnormal for all outputs or only a specific output? If so, ensure no bus contention where the output is also receiving an input. Also, check for shorts i.e known good unit vs suspected unit, thanks

Best Regards,

Michael.
