SN74CBT3251: Analog Switch/Muxes Solution Support 1.8V Vcc

Part Number: SN74CBT3251

Hi team,

 

My customer is looking for 8 channel analog switch solution that could support 1.8V Vcc, just like SN74CBT3251, but the min Vcc of SN74CBT3251 is 4V.

Do we have any solution to it? 

Thank you.

    Hello Fery,

    For future  reference you can use TI.com's parametric search under Switches & Multiplexers to more quickly find your solution as shown below:

    Unfortunately we do not have an 8 channel switch in our portfolio that can operate from with a Vcc of 1.8V to 5V.  The lowest voltage Vcc min we have for 8 to 1 mux switches is 2V and often at that voltage the on resistance of the switch becomes very nonlinear.  However, we have several 2 to 1 switches that can accommodate that Vcc range.  Below is just a few of the many we have.  You could cascade a few of these to achieve an 8 to 1 mux.  Could you me a few more details on what you are trying to accomplish with the switches?  With a few more details I may be able to provide you with a better alternative.
