Available via email: Informations from IC-, Transistor-, Diode- datasheets listed in this homepage. If some conditions are fulfilled I can send copies, scanns or photos.

No hardware, no parts, no prices,

No simulation datas, no software,

No actual manufacturer, no supplier,

Only a few of original .PDF- datasheets. No conversion to PDF.

This collection of semiconductor datasheets / databooks is the result of my hobby. Answering to your question happens not professionally and only if I have the time. I am pleased if I can help you.

Grown in the years 1970 - 1996 , the collection was not actualisated continually.

Help available via email :

No information on actual manufacturer or supplier available! I can try to select the old manufacturer contained in the datasheet.

Brief Informations: I can select maximum ratings and characteristics from the datasheet, or e.g. the pinning for an IC, or your special problem if I find the answer from the datasheet, and send via email. This work is without guaranty of course.

Detailed infos and selfmade diagrams: If I understand your big problem ( To repair an old equipment, to understand the function, to make a new design, to collect for museum, and so on ) I can summarize all useful infos. If you need a replacement I will note the critical data needed for your search, but I don't possess replacement lists. Of course, if you find a possible replacement I will test its data too if I have the datasheet.

Full datasheets or original diagrams: If you prefer the original data or if you need original diagrams, images and applications, I will make copies, scans or photos, see below. Perhaps you need patience if the datasheet has more than 10 pages because of the priority of brief answers. Besides I don't converse the scanns to .PDFs. I prefer .GIFs for the email appendix.

Copies, scanns or photos of the datasheet

For a copy one has to pay attention to the copyright, normally holded by the original manufacturer or by the publisher of the databook. Therefore I copy (scan,photo) only if the manufacturer no more exists, or if he is not able to deliver a datasheet from a part out of production.
Your first step therefore is to contact the manufacturer and to check the possibilities to receive the informations directly.

Your second step: How many pages has the datasheet? For Integrated Circuits and Modules the list of available datasheets has on the right column the number of pages. On the top of the list you will find the legend. A Transistor- or Diode-datasheet has <=4 pages, very seldom there is a volume of 8 pages.

Step 3 : Do you need all pages of the datasheet? Unfortunately only 60% of my datasheets are suitable for easy scans. Scans are very difficult if a large paper format contains diagrams inscibed using very small fonts, only 0.5 to 1 mm hight. Therefore I need high resolution. To reduce the volume one has to scan different areas of the page using different resolutions, but this needs too much of my precious time. Many datasheets ( listed as 3 B, 4 B...) are contained in a thick databook. In this case I prefer to make b/w photos or gray scaled photos having the disadvantage of less contrast and big data volume.

Step 4 : Please test your maximum allowed email appendix volume and send this information with your wishes.

Costs for copies and postal tariff

This is my hobby, all helps are for free. Little copies are also for free. For more than 10 pages I'm grateful if you send a cheap share in copy- costs as you take for adequate. What about the postal tariff? The old method using IRCs (International Reply Coupons, available at your post office) is hard and tedious as for you as for mi. But sometimes this is the only possible way. If I see the answer via email appendix is impossible I will inform you of the number of needed IRCs to pay the postal tariff.

I have a try to conceal my email and postal address against machines:
