SN74LV4051A-Q1: Signal Channel Pin impedance to GND Consult

Part Number: SN74LV4051A-Q1

Hi Team,

Do we have Pin impedance to GND data of signal channel here, like pin Yx/COM? And whether the pin impedance to GND will be changed or not when channel is on/off?

Best,

Stanley

    Hi Stanley,

    I am not clear on exactly what you are describing in regards to the pin impedance to GND. Do you have an illustration on what parameter you are curious about? There is no connection between the input pins and GND unless there is an event where the inputs goes more than 0.5V below ground, the ESD protection diode between the input and GND will begin to conduct.

    Let me know if you can clarify the question a bit more and would be happy to help out here.

    Thanks!

    This is specified as leakage current. It is not different for on or off.
