CD4053B-Q1: The description of truth table in datasheet page 16.

Cage Chen

Part Number: CD4053B-Q1

Hi Expert,

     We noticed that the truth table of CD4053B-Q1 in datasheet page 16 is confusing.

     No matter the high or low of A, B, C, the ON CHANNEL(s) are all ay or by or cy?

     Could you help us to confirm it?

     Thanks a lot for helping.

Best regards, Cage.

    Cage,

    The truth table within the datasheet has a typo here. The functional diagram on page 1 shows the proper through path for the switches:
     


    The actual truth table should read

    INHIBIT

    C

    B

    A

    On Channel(s)

    L

    L

    L

    L

    ax or bx or cx

    L

    H

    H

    H

    ay or by or cy

    H

    X

    X

    X

    None


    This also matches the truth table on page 17 of the datasheet from the same product made for different applications parameters

    Sorry for the confusion and I hope this resolves the issue. Thanks for finding this and bringing it to our attention. We’ll add this to the backlog and make the changes on the datasheet accordingly.

    Thanks,
