TMUX1119: High ripple due to switching

Hello Krunal,

Is the ripple on VDD? 

What is the frequency of the signal? 

If the ripple is on VDD it seems the signal is exceeding its recommended operational conditions. 

Please answer questions above for clarification. 

Thanks,

Nir 

Hello Nir,

The ripple is observed at D and the frequency is 1 MHz. As per datasheet, Max voltage limit of VDD is 5.5 V and for D is till VDD. 

So, i think exceeding the recommendation limit is not case.

Thanks,

Hello Nir,

Thanks for recommendation. By adding decoupling capacitor of 24.7nF, output is coming from "D" pin looks better than before and ripple becomes less.

Thanks,
