TS5A22364-Q1: Can the input of this switch be used as an output? Will a 5V pull up distort mic signal?

Part Number: TS5A22364-Q1

e2e,

[Q1]

My schematic is that input is COMx and out is NOx, but in is NOx and out is COMx in datasheet.

Is it allowable from COMx to NOx?

 

[Q2]

VCC=3.3V and signal range is ±2V.

5V Pull-up is placed on NO1 for MIC signal diagnostic. I'm concerned that 5V PU could distort MIC signal.

Does this make any distort on MIC signal?

If it could distort MIC signal, what about placing bypass capacitor in series to remove the DC bias?

 

 

Thank you,

Adam
