Obsolete component replacement/alternative

Other Parts Discussed in Thread: CD4043B

HCC4043 is now obsolete and I need to identify a replacement component as soon as possible.


Could you provide me with information/details of an alternative component if there is one available so I can create a purchase order and forward our production?

Thank you in advance, regards,

Ian Pound

  • The HCC4043 is not made by TI.

    It is a clone of the CD4043B, which is not obsolete.

    The HD647180X is not compatible with any MCU made by anybody else; you'd have to ask HitachiRenesas.

  • Sorry I sent the wrong information to you.

    The HCC4043 data is attached and I would like you to confirm that CD4043 or any other of your devices can be used to replace the obsolete component.

    Thank you, best regards,

  • As I said, the HCC4043 is a clone of the CD4043. If you compare its parameters with those in the CD4043B datasheet, you will see that they are identical.
