Does TI have a 12:1 analog MUX that can operate from 1.8 V supply?

Yoshiki-san,

I found a couple 1:16 muxes on the TI.com switch selection tool like the CD4067B that will pass 1.8 V signals through the signal path. 

What type of signal are you trying to pass through the 1:12 mux? 

Do you have any other performance requirements of the switch other than passing 1.8V signal?  Bandwidth, datarate, on-state resistance, etc? 

Thank you,

Adam

Aozer,

Currently we do not have a 1:12 mux that will operate with a 1.8 V supply.  Are you able to use a different voltage rail or a boost converter?

When I filtered the TI.com switch selection tool it returned 60 other muxes that operate with 1.8V supply.   Like your current solution you could get creative using multiple ICs.

What do you think about using 3x TS3A44159 devices or 2x TS3A127518E devices to create a 1:12 mux?

Thank you,

Adam

  

Ravindra,

I wasn't thinking about using the TS3A27518E with shorting the common together.   I was thinking of using the 12 x 1:2 muxes in series to create a 1:12 mux.

Yoshiki san ,

Is there other supply which could be used on the board too ? There are 1:8 or 1:16 Muxes which operate from 2V , although the I/O ports will transfer 1.8V signals through them . I was considering a single CD74HC4067 1:16 Mux OR 2 *SN74LV4051A (or SN74CBTLV3251)+ single 1:2 switch.
