I'm looking for information (preferably datasheets) for the two General semiconductor devices: AY-1-5050P & AY-1-2020P.
I know the 5050 is a 7 stage counter but I have no idea what the 2020 is and I haven't been able to find any reference to it. I was given the info by a colleague who asked if I could help find datasheets for these devices. Could there be a error in the part number? Is there a 2820, 2028, 2828 or something similar that may have been misread as 2020?
Any information or a pointer in the direction would be appreciated. Thanks.
