[FAQ] SN74CB3Q3253: What to do with unused pins. Asking for the SN74CB3Q3253 output pin can be floating or not

Part Number: SN74CB3Q3253

Hi team,

Can SN74CB3Q3253 pin 3/4/6/10/12/13 can be floating if unused?

BR,
SHH

  • SHH,

    Yes, You many leave unused I/O pins floating.  

    Please see the switches and multiplexers FAQ page.

    Why did you choose the SN74CB3Q3253 2-channel 4:1 switch? What are you doing that you have so many unused pins? 

    Have you looked at a 2-channel 1:1 device like the SN74CB3Q3305 instead?  I found this on the ti.com switch search tool.

    Thank you,

    Adam
