Level shifter

Other Parts Discussed in Thread: CD40109B, LM6511, LM311


We have to level shift 15V to 5V, which is input to gate driver. So,can you suggest TI parts with low propogational delay for the same.

  • What do you mean with "low"?

    The only logic devices for voltages above 5 V are in the CD4000 family. The CD40109B can be used as a high-to-low shifter, with a propagation delay of at most 500 ns at 25 °C.

    Comparators like the LM6511 or LM311 are faster.
