SN74CBT16214C: Searching for a Similar Product But Higher Voltage Handling

Part Number: SN74CBT16214C
Other Parts Discussed in Thread: TMUX6209, TMUX6234, TMUX4051

Hello E2E Experts,

Currently we working on one configuration where we need the similar product like SN74CBT16214CDGGR where the selection of input channels are done from 3 sets of 12 inputs
but with SN74CBT16214CDGGR there is limitation of the voltages till 7 Volt

could you please help to provide any TI products where 3 sets of 12 inputs or more channels and output will selected from 3 sets & VOLTAGES handling capability > 30V

Please let us know if any products are available like this.

  • The nearest solution for such high-voltage signals would be 6× TMUX6209 (4:1, two channels).

  • Hi,

    The SN74CBT16214CDGGR device has a absolute maximum limit of 7V, this is not the recommended operating range (which is 5.5V). Clemens is correct the closest option would be a multi-chip option would be the TMUX6209 (6× TMUX6209 (4:1, two channels)).

    Thank you,

    Arya 

  • Hi Arya & Clemens,

    Thanks for your inputs!

    Regarding the TMUX6209 / TMUX6234 / TMUX 7234 parts: 

    Can we use these Analog MUX switches to work with analog IOs i.e.  Analog input range - 0 to 24V, low frequency < 100Hz, Analog Output range - 0 to 10V, low frequency < 100 Hz?

    Thank you,

    Srinivas

  • Why are the input and output voltage ranges different? A closed switch simply connects the selected input and output pins, so their voltages will be the same.

  • I meant that we would like to give both analog input and analog output as two different inputs to the TMUX IC - based on the selection control logic of TMUX - we can either select the MUX output to be as "Analog input (0-24V)" or an "Analog Output (0-10V)". Hope you got this...

    1. The question here is whether this TMUX switch IC works/support for such analog signals?

    2. Also a new question, we would like to know whether this TMUX IC works/supports RS422 signals (such as consider 19200 bps or 115200 bps) ?

  • Hi Srinivas,

    The our muxes acts as a bidirectional switch for any voltage within the device range. Another device could be the TMUX4051.

    This does have a voltage range for VDD is 5-24V, not 0-24V. As long as the I/O voltages are within the device specification which in this case for the TMUX4051 would be VSS to VDD.

    In regards to the RS422, the data rate are very low so this is not a issue for the mux, as long as the RS422 is not in the negative voltage range.

    Thank you,
    Arya
