Teledyne Semi. obsolete IC info needed 1

[jkennard]

I am looking for the data sheets and/or description of the pinouts for the following Teledyne Semiconductor digital devices (late 60's to early 70's vintage):

312CJ
321CJ
342CJ

Suggestion: Try older catalogs, e.g. Newark Electronics, Allied Electronics, etc. and Product Substitute pages. Also, contact the Teledyne Industries for more info

etc.

Thanks jbartos for your input. I have searched the old catalogs, and various product substitute pages and run web searches. At galco.com the data sheets are not available. There is no information on these devices on the teledynewireless site. Teledyne Semiconductor was changed to Telcom Semiconductor in the mid 90's, and I believe it has since been acquired by Microchip. I conducted a search for these devices on the Microchip website but got a response of "devices not found"

If someone out there has an old IC Master set of catalogs about 1970 vintage maybe the information on these devices is included in there.

Have you tried

http://www.freetradezone.com

?
I have often found hard to find data sheets there.

Thanks Steve for your input.

YES, Freetradezone was the first site that I tried, but no data sheets for these devices existed. I have searched many websites for this information. I need someone to point me to a website that definitely has this information, and has previously checked it out for the availability of these data sheets.

Otherwise, the pinout info from an old copy of the IC MASTER would be helpful.

Can someone out there help?
