However, based on our understanding, this specification seems to describe the switch turn-on / turn-off delay, which is the propagation delay between the digital control signal and the analog output when the switch is turning ON or OFF. What we would like to confirm is the signal propagation delay through the switch path, from the analog input to the analog output. For reference, the attached screenshot is from the TI SN74AUC125RGYR datasheet. In that device, the parameter we are looking for is similar to tpd, while the tON / tOFF information in TS3A27518E seems to be more similar to tEN / tDIS. Could you please help confirm whether TS3A27518E has a tpd specification for the analog signal path, or whether TI has any estimated value or guidance for this parameter?

We do not have any reference designs for this device. 2. When this switch is on, it acts as a wire, so please design any biasing based on what you would do if a wire was in place instead.

As per the datasheet, the maximum rated ambient operating temperature (TA) for this IC is 85 &#176;C . Our application requires operation at an ambient temperature of up to 85 &#176;C under normal operating conditions. We would like to confirm the following: Whether continuous operation at 85 &#176;C ambient temperature is acceptable for this device If there are any recommended derating guidelines, thermal considerations, or reliability concerns when operating at this maximum ambient temperature Whether TI recommends maintaining any temperature margin below 85 &#176;C for long-term reliability Kindly confirm if our intended usage is within the safe and supported operating limits for the TS3L110PWR.

In the IBIS file, the series switch model has the capacitance value while the terminator is missing it. Yes, you are right the model is incorrect. As you said there should be an actual C_comp value in the terminator models. The TMUX121 has a typical Con of 1.7pF. You can edit the IBIS file to change the C_comp value to 1pF instead of 0pF. Another options is to create an IBIS model using passive components like explained here . Thanks, Nirhttps://e2e.ti.com/support/switches-multiplexers-group/switches-multiplexers/f/switches-multiplexers-forum/1641980/tmux121-ibis-and-s-parameter-models/6332810Tue, 05 May 2026 07:11:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:15ea1a8c-17eb-4f3a-8118-947112de9f81David MalpassAccording to the IBIS specification &quot;C_comp values are ignored for [Series MOSFET] models&quot;. Therefore any capacitance would need to be added using the C_comp of the actual pin models (i.e. TMUX121_SX_3P3V and TMUX121_DX_3P3V), presumably these should have a C_comp value equal approx Con/2 - however these pin models have C_comp set to 0pF) Do we need a call to try and resolve this rather than message ping-pong
