Hi,

I’m looking for a high-speed analog switch/multiplexer to toggle between two negative voltage levels: $-2.4V$ and $-5V$

Hi,

I'm working with a component that operates on a negative supply. I need to toggle it at a frequency of 10MHz. When I apply a voltage of -2.4V, the component is active, and when I apply -5V, it is inactive.

Hi, Tzafrir20 .

Could you please share more details on why you think this part may not be a good fit? Is it due to the switching spike? This information will help me identify the most suitable part for your application.

Best regards,
Christian

Hi, I expect to see switching between the voltages. In other words, a square wave at the output switching between the two inputs, and that is not what I am seeing.

Thank you very much.
