Course topics EE Lx 74ls12n Notes – A collection of topics related to constructing the class projects soldering, wire wrapping, debugging, etc. Their prices on some stuff is very 47ls21n, provided you can find what you need. This document discusses programming the Datasehet but much of the information also applies to other ATmega or ATtiny microcontrollers used in the class.
These parts are not normally used in current EELx projects. Many of their files are scans of pages from their printed databooks and the images come out looking pretty bad.
Jameco Electronics – We used to buy most of our stuff from Jameco before they “improved” their web site. Their inventory changes a lot so you might not be able to buy the same things six months from now.
Popular Electronics. 74LS 14P Dual 4 input AND Gate
Either way, they have a large collection of datasheets online and they are good quality. Fairchild Semiconductor – They used to have a good collection of very presentable datasheets but it looks like most of the 74LS ones have been removed. Many figures didn’t survive the translation too well or are missing datashfet.
Arduino basics with Tinker Danica. These devices contain two independent 4-input gates each of which performs the logic AND function.
Here’s some of the stuff we use and recommend. Datasheets for the newer parts were mostly obtained from the manufacturers or from Jameco and Digi-Key where we order most of our parts. These will be fixed someday, maybe. It will also get you on their mailing list for future catalogs. Some functions may be missing or not functioning.
