Part Number: TXB0304

Hi team,

My customer is using the TXB0304 IBIS module to do the simulation.

The module is as below:

They use the module with one shot.

But when they add the input in A, the input of B has large shot as below:

The wave are the input of B and in the TC,BC,WC simulation condition.

Can you help to comment what may be the cause？

Thanks a lot!

Hi Lacey,
Can you get a zoomed in shot of the red box region of the waveform? I'd like to see what's happening exactly on that falling edge.

Also, can you get the simulation schematic?

Hi Emrys,

Update the waveform.

Please help to check.

Thanks a lot!

In order to simulate this I need to see the full simulation schematic -- at least what is connected as a load and input.

Hi Emrys，
Does picture I post in the first one can show the simulation circuit?

No, the load conditions are not shown -- I need to know the transmission line length at a minimum -- there's also a resistor shown that doesn't have a value. It would be best if I can get a screenshot directly from the simulator.
