TS3A24157: TS3A24157 state of COM1/COM2 when V+ = 0V (Power OFF state)

Part Number: TS3A24157

Hi, 

I going to use TS3A24157 device.

 

I want to know what is the state of COM1/COM2 pins when V+ = 0 (POWER OFF state)

 

Is it connected to the NO pin or to NC pin or to none of the two pins (isolated)?

 

I can’t find this information in the data sheet

Thanks,

Shlomi

  • Shlomi,

    I searched the switches and multiplexers e2e forum for “TS3A24157” and the first post the comes up is TS3A24157: Connection between COM and NO/NC when VCC=0v that tells you TI does not guarantee the state of this switch without a valid supply voltage.

     


     

     

    You can use the ti.com switch search tool to find a device with the powered off protection feature that will guarantee a Hi-Z state when Vcc= 0V.

     


     


    Let us know if you need further help selection a switch? 

     

    Thank you,

    Adam
