You can also visit their store at Oxnard St. Contact Infomation If you have any amazing things you want to discuss with Tinkbox, don’t hesitate to contact us: They are all copyrighted by someone but we’re not going to worry about that.

The administrators are still migrating contents to our new home. Fairchild Semiconductor – They used to have a good collection of very presentable datasheets but it looks darasheet most of the 74LS ones have been removed.


Either way, they have a large collection of datasheets online and they are good quality. Parts in stock – This dztasheet a list of most of the parts that the EE class has in stock for project construction.

74LS21 Datasheet

Using the analog-to-digital conversion module on the ATmegaP microcontroller – An description of how the ADC module on the P works and how to configure it for doing conversions.

Product Group Product Description. Jameco Electronics – We used to buy most of our stuff from Jameco before they “improved” their web site. Some of the following documents are in PDF format. For information on the Freescale microcontrollers that were used in EE up until aboutand sample code for them, click here. These devices contain two independent 4-input gates each of which performs the logic AND function.

Order Information Free shipping. Some functions may be missing or not functioning.

All students should read this before starting construction of your project in the lab. For all your product inquiries, send us a message on our Contact Page with the Product Inquiry subject. Digi-Key – This is our other primary supplier. These were originally written for the ATmegaA and should run unchanged on that processor.

Engineered in the Philippines. Implements a modulo 5 up-down counter with binary outputs and decoded 1-of-5 outputs. The notes below mostly apply to both microcontrollers even if the description of the document only mentions one of them. Most are 74ls21h to test PALs on a demo board in the lab.


Other Services Custom Projects. However they do have a PDF of a pocket version of their logic data book.

They have a large inventory, the prices are reasonable, and we usually get the order pretty quickly. Most are not scanned images so if you can find these, it will be easier to read and print out.
