MC3486: internal PU high in input/out

Shu-Cheng LIN

Part Number: MC3486

Hi Sirs,

As title.

Does MC3486 have internal 5V pull high on I/O?

We wish the output level can same as input because output will connect to 3.3v MCU.

Thanks!!

    Hi Shu-Cheng,

    When outputting a high level, the "Y" output pins will pull the line up to the VCC voltage, which should be 5 V (+/- 5%). So, to connect to a 3.3-V MCU input I would recommend implementing level shifting. Please let me know if this isn't clear or if I have mis-understood your question.

    Regards,
