Part Number: CD54HC221

Hello Team,

Good day.

My Customer would like to ask if the CD54HC221 can be a replacement for their old device MM54HC221AJ/883C? 

Thanks in advance.

Regards,

Renan

    Hi Renan,

    These two are direct replacements

    MM54HC221AJ/883C seems to appear in DLA drawing 5962-87805 (Rev C), which it shares with CD54HC221

    Here's the part number table from the drawing:
