SN74LV4051A-Q1: Whether this device can be used for 1.8V

Part Number: SN74LV4051A-Q1

Dear team,

Could you please tell me whether our device can be used under 1.8V(power supply). Below first picture said the 1.8V is available, but in our datasheet(the second picture), the power supply'a range is 2-5.5V. Could you please tell me which one is right?

Thanks & Best Regards,


  • Hi Sherry,

    The SN74LV4051A-Q1 supports the supply voltage highlighted in the recommended operating conditions in the datasheet.

    if you specify the minimum voltage you want for your switch in the device selection table, you will get the list of recommended options. You can further filter/sort on the switch configuration and number of channels.

    Thanks you,


  • Hi Saminah,

    Yes, even though I filtered according to your recommendation, I still can see this device as below. However, in the datasheet this device can't work when the power supply is below 2V. Which one is correct, datasheet or below picture? My customer wants to find a device which can work under 1.8V(automotive rating), but it seems like we don't have such device. Do we have any new device which can meet his requirement?

  • Hi Sherry,

    I am looking into the device search tool to see why SN74LV4051A-Q1 is still showing up. You can refer to the datasheet that shows the correct information.

    We currently do not have a part that can work under 1.8V (automotive rating). I can provide this information to our product definition team and get back to you if we have a solution available in the near term.
