| On the [[:electronic:datasheet:sidebar|sidebar]] there is a list of component/device manufacturers, initially at least devices will be listed alphabetically by part number. If my collection gets large then other categorization schemes may be implemented. | On the [[:electronic:datasheet:sidebar|sidebar]] there is a list of component/device manufacturers, initially at least devices will be listed alphabetically by part number.

| | In the following “**n**” is a place holder for a digit, “**A**” for an alphabetic character, and “**X**” is either. |
| | |
| | “**nAn**” IC date codes\\ |
| | Many integrated circuits made in Asia used a three character code to state the year, month and week of manufacture.\\ |
| | Format //ymw//, so “6C4” means the 4th week of March 1986. |
| | |
| | ^//m//^Month| |
| | ^A|January| |
| | ^B|February| |
| | ^C|March| |
| | ^D|April| |
| | ^E|May| |
| | ^F|June| |
| | ^G|July| |
| | ^H|August| |
| | ^J|September| |
| | ^K|October| |
| | ^L|November| |
| | ^M|December| |
| | (NB "I" not used for month) |
| | |
| | |
| | “**nnnn**” IC date codes\\ |
| | Many integrated circuits have a four digit code to state the week and year of manufacture.\\ |
| | Format //yyww// or //wwyy//, so “8610” or 1086 for tenth week of 1986. |
| | |
| | |
| | |
| | “**nnXX**” IC date codes\\ |
| | Many integrated circuits made by Sharp in the 1980s used a four character code to state the year, month and week of manufacture.\\ |
| | Format //nymw//: Id digit, Last digit of year, Month, Week. So 921C means third week of January, 1982 |
| | ^//m//^Month| |
| | ^1|January| |
| | ^2|February| |
| | ^3|March| |
| | ^4|April| |
| | ^5|May| |
| | ^6|June| |
| | ^7|July| |
| | ^8|August| |
| | ^9|September| |
| | ^X|October| |
| | ^Y|November| |
| | ^Z|December| |
| | |
| | ^//w//^Week of month| |
| | ^A|Week 1| |
| | ^B|Week 2| |
| | ^C|Week 3| |
| | ^D|Week 4| |
| | ^E|Week 5| |
