Part Number: TMUX1208
For the input signal lines on the TMUX1208 (S1-S8), is there a specification for how much capacitance these pins can and should have? If caps are added on each signal line close to the pins, would that negatively or positively impact the part?
Thank you in advance for your support!
The TMUX1208 will have capacitance on the (S1-S8) pins which is stated in the on and off capacitance spec in the datasheet.
Adding external caps on these pins will add additional capacitance to the signal path but will not effect the device.
Why are you wanting to add additional capacitance to the switch? What are you connected to the S and D pins?
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to Adam Torma:
Thank you for the note! The reason for adding additional capacitance to the line is to help filter some of the signals coming into the mux. The S pins are connected to voltage dividers and analog signals throughout the system and the D pin is connected to a processor. Very similar to the application page in the datasheet.
I just wanted to ensure that adding capacitance to the S lines would not cause abnormal oscillations or anything like that.
Thank you for the support!
