TMUX1574: closest TI equivalent to PI3A412 ?

Part Number: TMUX1574


Do we have an alternative to PI3A412 (4Ch SPDT. 3.3V)?

The TI.COM cross-ref just refers to our MUX page so I guess we do not have a 1-to-1 equivalent. Correct?

Thanks in advance,


  • Hi A.

    So we don't have any crosses because the PI3A412 current limit is higher than the vast majority of our portfolio - we do have 1 part I think that can support the current but its different it every other way that's not current and if current is far off we typically don't consider it a cross of Q or S standard which is generally what we try to have in online cross reference tool for our analog multiplexers/switches. 

    So if we have a good cross is actually going to depend on application because we might - but how this part is being used may disqualify our solutions. So if you can share application details - at least in voltage levels (signal), power level, current through switch, required bandwidth, leakage required, and finally any other application details that pertain to the mux I will be able to determine if we have a good cross or not - it may be the 1574 but it could be a different part altogether. And if you can share the End Equipment that could also help as we do have certain parts we recommend for various End equipment.

    Please let me know!
