TS3DDR4000: For NAND I/F.

Part Number: TS3DDR4000
Other Parts Discussed in Thread: TMUX646

Hi team,

I'm looking for a 1:4 multiplexer with NAND I/F.
It is like MX0141K(IDT/Renesas).

Can I use TS3DDR4000 with NANDI/F?

If you have some application notes,please share us.

Sincerely.
Kengo.

    (Earlier question: SN74CBT16390: Replacing "MX0141KA0".)

    You can use any switch that supports the required voltage and the required speed.

    I guess you are asking about the TS3DDR4000 because you need 12 channels?

    All application notes are linked from the product web page; for the TS3DDR4000, see the EVM user's guide.

    Hi Kengo,

    The TS3DDR4000 is a 1:2 mux, not a 1:4 like the competitor device but as Clemens mentioned, as long as the voltage/bandwidth is within the datasheet specs, then it will work. Our analog multiplexers pass through the input signal to the output, they do not re-drive the signal.

    What signal voltage, bandwidth, configuration (1:4, 1:2), and channel count are you looking for? We offer some higher channel count 1:4 multiplexers but they may not meet the bandwidth or voltage requirements.

    For more information on our multiplexers, we have an extensive collection of FAQs here and our library of multiplexer application notes are here.

    Thanks,
    Tyler

    I’m not sure if TMUX646ZECR can be used for MX0141K replacement. Do you think it is possible?

    Hi Adam,

    There are a handful of differences between the devices but it is possible to use the TMUX646. If your application only requires a 2:1 configuration instead of a 4:1 it will work. An example of the difference can be seen in the picture below:

    The TMUX646 offers a high bandwidth of 6GHz allowing it to pass high speed data. It is an analog multiplexer, meaning that it does not redrive the signal with a buffer, it only passes through the input signal less a small attenuation from RON. The TMUX646 has 10 channels compared to the competitors 8 channels. It is offered in a small package size, saving board space as well.

    Thanks,
    Tyler
