TS3A4751: When input is Hi-Z

When IN is low, the NO and COM pins are disconnected from each other, i.e., they are Hi-Z.

When IN is high, the NO and COM pins are connected. If there is no external signal applied, both pins are floating.

Hey David,

As Clemens mentioned, the IN pin controls the state of the connection between NO, determining whether it is connected or disconnected.

From section 7.4 in the datasheet you can see the truth table of how this device functions given the IN input.


When IN is L, the NO to COM path is HI-Z.

Thanks,
Rami

When IN is H, if NO is Hi-Z, COM is Hi-Z.

Is this correct?

Yes.
