Hi to all,
Just tidying up my bits box and came across these ICs!
They are 16 pin dip and bear the numbers 54176174 japan, 42C40P, 1897, 8914HB. They will probably be from the 70s or 80s!
I think they could be 54 Series Logic ICs but am baffled by the numbering system as the 54s usually have some letters immediately after the 54 then the rest of the number.
If anyone knows what they are i would be very happy to find out, I have googled all the numbers on the IC but only come up with a sheet if I remove some of the numbers from the end of the 54xxxxxx and then it seems to be a flip flop of some kind, but the number is making me very uncertain.
Thanks........Al
