Part Number: SN74LVC1G3157
I want to find a Analog MUX for4:2 or 2:1， need very small leakage current (50nA) for input pin.
I want to use it to measure voltage , but it has 3.4MΩ impedance（NTC has very high impedance at low temperature）. This is why I need input pin has very small leakage current.
Analog MUX :
4:2 or 2:1.
Input Pin Leakage current: 50nA at -40°to -20°, I couldn't find these data or waveform at datasheet.
Need auto Q1 version.
Power supply: 3.3V
Do you have some good suggestion for this application?
Please see this post about the SN74LV4052A and leakage current:
We also offer a 2:1 version of this device called the SN74LV4053-Q1 which will also have similar leakage current because they are the same types of switching FETs but in a different configuration. I understand that the SN74LV4053A-Q1 has one more 2:1 channel than your application needs, but we can repeat this experiment for 2 channel 2:1 such as a TS5A23157-Q1.
In the future, you can visit the ti site and search the parameters you have listed above such as the snippet below:

In reply to Wentao Zeng:
I went into lab and ran a quick temperature sample of the TS5A23157-Q1 that I mentioned in the previous post. Please find the curve for the leakage current swept across temperature below:
Let me know if this works for your application or not.
