Part Number: TS5A23159
Where can I find ibis model for TS5A23159?
Models for TI devices are found in the tools and software section of the device product folders.
Unfortunately there are no models available for this device.
These are passive FET switches and are not buffered so an Input/output Buffer Information Specification IBIS model wouldn't be appropriate.
What are you wanting to check with the model?
You can create a simple lumped model using the information provided in the datasheet for different specifications depending on your application.
The above diagram comes from this app note.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to Adam Torma:
I just want to simulate digital signal at 100 MHz. Is TS5A23157-Q1 also passive FET switch? Thank you.
In reply to Dung Huynh:
If you would like to use a 100MHz clock we would recommend using a device with at least 3 times the clock frequency. You should select a device with at least 300MHz bandwidth. The TS5A23159 devices only has 100MHz bandwidth which means that device will attenuate a 100MHz signal -3dB.
You can filter the ti.com switch search tool for 2-channel, 2:1, >300MHz bandwidth and find better devices for your application with much lower on-state capacitance which can slow down your clock edges. What do you think about using the TMUX136 or TMUX1072?
Yes, the TS5A23157-Q1 is also a passive FET switch like all of them on the switch search tool.
The TS5A23157-Q1 devices has better bandwidth and capacitance performance than the TS5A23159 and may work in your system depending on your system signal chain performance. I would not recommended using the TS5A23159 for a 100MHz clock application because yes theoretically the bandwidth matches the clock frequency but in practice you need margin in your signal chain design.
Just to highlight key features of TMUX1072 as compared to TS5A23159 -
It is the first 2 channel 2:1 Mux in the industry with 18V Over-voltage protection and
TMUX1072 comes in both leaded (TSSOP) and leadless (QFN) small package.
