Part Number: SN74CBTLV3257

Hi All,


My Automotive customer designs cluster.

Here he is using 74CBTLV3257 in package DHVQFN16.

Is this a bi-directional switch? Is it the cheapest and more convenient device we can offer with these specs or we have something better/newer?


 Many Thanks,


  • Hi Antonio,

    All switches and multiplexers we support are bi-directional.

    We have the new TMUX part- the TMUX1574 with lower 2-Ω RON, wider supply range (1.8V-5V) and more features like 1.8-V compatible control inputs, Fail-safe logic compared to the 74CBTLV3257. 

    It is also available in the QFN package.

    Here is a comparison of the two parts.

    For automotive application, we have the new SN3257-Q1 which is available in the DYY package. The DYY is a small leaded package that reduces potentially manufacturing issues seen with QFN’s in automotive.
