Is the MC6821 still in production? Who made them? Authenticity check?

I'm going to ask this as I believe NXP owns Freescale's IP now. Sorry if I'm confused or if this is not allowed. 


I'm working on an older board with an MC68B21P. I don't think these are still in production, but wanted to confirm that before buying anything from anyone. 


Looking for a replacement I see a Freescale variant offered online by non-franchise distributors, but no documentation by Freescale indicating they made these. Can you tell me if this is correct or if this part has been remarked incorrectly? 


Thank you for your time. 


Again, sorry if this post is not allowed. Not sure where to ask this due to companies being sold off, closing, etc.
