TMUX6112: Undesired Spikes on I/O pin while switching

Md Faisal Rahman
Prodigy 150 points
Part Number: TMUX6112

Hello

I am using TMUX6112 to build a switching circui.Here  the rise and fall time of the select signal is 150ns and the IC is powered by Vdd = 10V (single). I can see the spikes on the Output pins as well as on the input pins with reduced amplitude on the out when the switching occurs. I can also  see spikes during the switching even when there is no power provided to  the TMUX6112 IC. I am confused if it is for bypass/decoupling capacitor or some other reason it behind this. I have used decoupling capacitor of 0.1uF very close to Vdd and VS. Please advice.

Above picture represents the situation when the IC is turned of .Cyan color represents the output signal and the purple color represents the SEL  input signal. Can see spikes on the output pin when switching in SEL happens.

 

Above picture represents the situation when the IC is turned on . Green color represents the input signal, Cyan color represents the output signal and the purple color represents the SEL  input signal. Can see spikes at both input and output pins when switching in SEL happens.

Thanks

Faisal
