74LS21 Datasheet, PDF – Alldatasheet

The notes below mostly apply to both microcontrollers even if the description of the document only mentions one of them. Typical parameters can and do vary in different applications. These parts are not normally used in current EELx projects. None of these sites are particulary easy to use if you don’t know what part you are dtasheet for.

We have no experience using the program at this time but it’s probably worth checking datashset. All students should read this before starting construction of your project in the lab. Other Atmel microcontroller documents and links AVR microcontroller interrupt vectors – A list of the interrupt vector names for the AVR microcontrollers listed above. Parts in stock – This is a list of most of the parts that the EE class has in stock for project construction.

Datasheets for the newer parts were mostly obtained from the manufacturers or from Jameco and Digi-Key where we datasgeet most of our parts. It’s definitely worth at least one trip there just to see the place, and its storage area outside in the back.

They may have absorbed Motorola’s TTL product line, or at least their tech library. It’s now more difficult to find stuff on the web site so you may be better off requesting a printed catalog or looking through the PDF version of the printed catalog. However the size of the catalog sometimes make it hard to find things. Skip to main content. 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.

Mega R3 Arduin This document discusses programming the ATmegaP but much of the information also applies to other ATmega or ATtiny microcontrollers used in the class. Powered by Rethink Tech Inc. S – Controls an LED with a switch.

All operating parameters, including Typicals must be validated for each customer application by customers technical experts. Datasheet 74LS21 Download Report. For all your product inquiries, send us a message on our Contact Page with the Product Inquiry subject. Newark and Mouser Electronics – These datzsheet are major suppliers to the electronics industry with very large inventories. Motorola Literature Distribution; P.

Jameco Electronics – We used to buy most of our stuff from Jameco before they “improved” their web site. Atmel Microcontrollers For information on the Freescale microcontrollers that were used in EE up until aboutand sample code for them, click here.

Output can be confirmed with an oscilloscope. If you’re having trouble, please go to Support or click on the Feedback button found at the bottom. Search form Search this site. Here’s some of the stuff we use and recommend.

Their prices on some stuff is very good, provided you can find what you need. It will also get you on their mailing list for future catalogs. However they do have a PDF of a pocket version of their logic data book. Not more than one output should be shorted at a time, nor for more datashret 1 second.

Implements a 3-bit up-down Gray code counter with binary outputs and the seven-segment display outputs the message “EE L”.

Their inventory changes a lot so you might not be able to buy the same things six months from now. 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. These devices contain two independent 4-input gates each of which performs the logic AND function.
