CLICK HERE for the TTL and CMOS logic listings!

This page contains links to datasheets for all the IC's used in my projects, click the part number to read the datasheet. Some of these I scanned myself, others are located on others' pages or the manufacturer's website. If there are any broken links tell me. To read these datasheets you need to install Adobe Acrobat if you haven't already done so. The scanned datasheets are sometimes easiest to read if you select "Actual Size" in Adobe Acrobat's "View" menu.

A number of these parts are obsolete, and several more will probably become obsolete very soon. I have saved local copies of all of the datasheets linked here, so that they will be preserved if the manufacturers decide to remove the datasheets from their websites. In this case I will replace the URL with a local link. If you find any broken links, let me know.

Many IC's are made by multiple manufacturers, and there have been many rounds of mergers, aquisitions and consolidations in the semiconductor industry. Therefore the manufacturers listed here are not necessarily the ones whose IC's I used, but in all cases chips from a different manufacturer should be interchangeable. In general 74nn chips and 74LSnn chips can also be interchanged, I simply used what was available to me at the time.

[Note 1] The 74100 is a dual 4-bit latch, and I used four in my frequency counter project. This device has long been obsolete and was never made in a 74LS100 version. It is so obsolete I couldn't find its datasheet anywhere on the web. It was packaged in a 24-pin DIL and several pins were unused. Suitable replacements would be the 74LS373 or 74LS273. The reason I used the 74100 was that most of my projects were made out of scrap, and usually designed around whatever parts I could find: in this case I just happened to find four 74100's. On 20-Dec-03 I received an email from Walter Geeraert PE1ABR in which he attached the 74100 datasheet, many thanks Walter!

[Note 2] Thanks to Jos Leandro for telling me about the 4464 (64K x 4-bit dynamic RAM) datasheet he hosts on his excellent web page

[Note 3] This Z80 datasheet was scanned from my old paper copy. This is an original Zilog datasheet, not one of the licensed Z80 equivalents such as the Z8400 by ST Microelectronics. As far as I know this is the ONLY online Zilog Z80 datasheet. The Z8400 datasheet does give more detailed information on various aspects of the Z80.
