TMUX1072: TMUX1072 as Digital Multiplexer.

Part Number: TMUX1072
Other Parts Discussed in Thread: CD74HCT4066, CD74HC4066, CD4066B, SN74LVC1G66, SN74HC4066, SN74LV4066A


We are using TMUX1072 in our design for SPI and some digital signals switching.

Since it is an analog multiplexer, Can use TMUX1072 to switch digital signals also? is that OK?

Thanks and Regards,

Pedaiah G.

  • Yes.

    3 Analog Versus Digital Signal Switches
    TI offers a wide variety of signal switches, and sometimes the nomenclature can be confusing to the point of implying limited functionality for a device or family. See details below on digital vs analog, bus switch and bi-directional functionality of switches.
    Digital switch. Designed to pass (or isolate) digital signal levels. May exhibit the capability to satisfactorily pass analog signals. Examples are CBT and CBTLV switch families.
    Analog switch. Designed to pass (or isolate) analog signals. Often exhibits good digital signal performance as well. Examples are TMUX11xx, TMUX61xx, TMUX12xx, TMUX15xx, CD4066B, CD74HCT4066, CD74HC4066, SN74HC4066, SN74LV4066A, and SN74LVC1G66 switches. TI's analog and digital bus switches are electrically equivalent and both share the common switch architectures found in the semiconductor industry.
    Bus switch. Digital switches designed for multi-bit switching in computing applications. Examples are CBT and CBTLV switch families.
    Typically, the high channel count switches in the TI muxes and switches portfolio are labeled as "digital bus switches" because digital buses usually have many more signal paths than analog signal paths for their common use of transmitting 8, 16, and 32 bits of data. As TI's switch portfolio continues to expand this loose distinction between analog and digital devices are becoming irrelevant. More details can be found in Switches and muxes: What are switches and multiplexers?.
  • Hi Pedaiah,

    All of our multiplexers/signal switches can handle digital signals. As long as your frequency and voltage signal are within the specification of the device you are using, there will be no issue.
