SN74LVC4245A: Voltage Translation 3.3V to 5V with HZ Output

Part Number: SN74LVC4245A
Other Parts Discussed in Thread: SN74LV4T125

Dear Community,

I am looking for a voltage translation device like the SN74LVC4245A but with only 4 bit instead of 8.

I also only need one direction from 3.3V to 5V but I need enable to put my output in 3 state.

Many Thank for any advice, as I didn't found something through the search function.

Best Regards,

Xavier

  • Hi Xavier,

    Would you consider using the SN74LV4T125?
  • Hi Xavier,

    I am curious about the search you made to narrow down.
    Did you use the parametric serch tool on ti.com?

    I have filetered the parametric search to find out 5.5V support with 4bits here below.
    www.ti.com/.../products.html

    Your feedback may also be helpful to us in redesiging the parametric search to be more helpful
  • Dear Shreyas,

    many thank for your help - I will check if it's suiting my needs.

    Concerning your question:

    I look to find a product trough the search function in: product => interface => voltage level translation

    Then I select: bit 4 and / VCCA max both 5.5V and 5.25V.

    I didn't though, that there are transceiver with only one supply as I usually know type with two supply (one for each side).

    So I didn't found this result.

    Many Thanks for your help.

    best Regards,

    Xavier

  • Thanks for the feedback Xavier. This is helpful.We do have unidirectional single supply translation family LV1T which can work from 1.65 to 5.5V. since there is no Vcca and Vccb, this can lead to confusion.

    I believe you used the quick search and used the Vcca to filter it.
    Using Vcc min/ max pointed to the right part. We will take this into our consideration while redesigning our search.
