MUX36S16: Technical question regarding the supply voltage conditions

Part Number: MUX36S16
Other Parts Discussed in Thread: CD74HC4067

Tool/software:

Hi team,

I just received a question TQ regarding the possible working conditions.


Apperently they are looking for an alternative for ADG706BRUZ-REEL7.

I suggested MUX36S16IPWR but they are claiming that our device can not operate with the same supply voltage as competition and needs higher voltages. I am confused because the data sheet clearly says that the supply voltage goes up to 40V for Vdd but doesn't need it necessarily right?
Now I asked specifically what supply they are using for the mux!

They are using the following:

  • Vdd: -0.3 V to +7 V
  • Vss: +0.3 V to –3.5 V

Can you please help me and explain if this will also work with our device or not?
If not than I am missing something.

Thank you in advance.

Best regards,
Rosario

    The absolute maximum ratings do not matter. For the device to work correctly, you need to stay inside the recommended operating conditions.

    The ADG706 works between 1.8 V and 5.5 V. The MUX36S16 requires at least 10 V. The only 1:16 mux with a similar voltage range is the CD74HC4067, with a different pinout and a much higher on resistance.
