What is it? It isn't worth digging out 40 old books with nothing more than a part number. MM covered memory chips and some other types, IIRC

AFAIK it's a 2-wire bus encoder/d=E9coder.
Ok, I really hope you can help, Michael. TIA.

Were you bluffing, or are you still stuck in data books ?

Trying to get to them. I'm 100% disabled and my library is currently full of boxes, blocking the shelves while a breaker box is to be replaced in the next room.

Is this the old garage door remote control chip usually paired with a DIPswitch for "security code"?
I'm 90% sure it predates rolling codes.

I found 21 of my National Semiconductors databooks, but no MM57410. I did find a MM57409 in the 1987 Microcontroller Databook. Maybe someone has a newer version?
The MM57409 is listed as a 'Super Number Cruncher'.
Have you tried conticting the guy selling them on Ebay? He might have the data sheet, since he has so many availible.

Ok, thank you for trying anyway.
Nah, MM57410 is definitely a 2-wire bus encoder/decoder.
Yes I tried - but no reply so far.
