TMUXS7614D: Ron performance, Supply condition and GND noise influence

Taketo Sato

Part Number: TMUXS7614D

Tool/software:

Hello team,

Is there difference on Ron value between +/-5V dual supplies and +10V single supply condition?

It would be helpful if you could give some data or explanation.

I would like to understand also how GND node fluctuation will affect Ron value. Any comment on it would be helpful.

Best regards,

    The transmission gates are necessarily powered and controlled by the voltages that define the valid voltage range (VSS and VDD), so Ron depends only on the total voltage between these supply rails.

    If GND has noise, you might get problems with the digital control signals, but Ron should not be affected.
