Part Number: SN74AXC4T774-Q1
Other Parts Discussed in Thread: SN74LVC1G17-Q1, TXS0108E-Q1

Hi Experts,

For below application, could you please recommend a cost-effective automotive voltage translator solution? I came up two ideas, which one is better? Do you have any other recommendation? Thank you very much!

    For unidirectional downtranslation (MISO), you can use a buffer with an overvoltage-tolerant input, e.g., SN74LVC1G17-Q1.

    If all signals work with pull-up resistors, it's possible to use a single TXS0108E-Q1.

    What frequencies are needed?
