Hi Team,

Customer is designing TS3A44159.

Would you please provide comment on the schematic? Can port 4 directly be floating?

  • Hi SHH,

    Unfortunately I am not able to access box where the schematic is,could you link the schematic in another way?

    However with respect to leaving pins floating, you can see some commentary at our  e2e switches FAQ page:

    Can I leave unused pins floating?

    This training video answers this question for all potentially unused pins of a device: signal pins, control pins, VSS, No Connect pins, and thermal pads.

    • Switch control inputs must always have a defined state. If the device does not have internal pullup or pulldown resistors, the pin must be tied to a known voltage.
    • Switch signal input/output pins may be left floating. In high speed applications, best practice is to terminate these unused pins to GND

    Hi SHH,

    I don't see any issues with the schematic as shown. Just make sure that the logic thresholds for the IN pins can be met by your system. 

    Best Regards,

    Parker
