Implements a 3-bit up-down Gray code counter with binary outputs and the seven-segment display outputs the message “EE L”. These will be fixed someday, maybe. How to Make Learning More Fun?

S – Displays a sequence of hexadecimal numbers on a seven-segment display. However the size of the catalog sometimes make it hard to find things. Ql5 datasheet pdf QL5 datasheet, Others were snagged from web sites wherever we could find them. Skip to main content.

The notes below mostly apply to both microcontrollers even if the description of the document only mentions one of them. Ql5 datasheet pdf -? Typical parameters can and do vary in different applications. S – Controls an LED with a switch. Should Buyer purchase or use Motorola products for any such unintended or unauthorized application, Buyer shall indemnify and hold Motorola and its officers, employees, subsidiaries, affiliates, and distributors harmless against all claims, costs, damages, and expenses, and reasonable attorney fees arising out of, directly or indirectly, any claim of personal injury or death associated with such unintended or unauthorized use, even if such claim alleges that Motorola was negligent regarding the design or manufacture of the part.

These sample schematics for devices unrelated to the class projects are similar to the types of schematics that should be produced for your project. Implements a 3-bit up-down binary counter with binary outputs and seven-segment display outputs. For information on the Freescale microcontrollers that were used in EE up until aboutand sample code for them, click here.


Arduino basics with Tinker Danica. All students should read this before starting construction of your project in the lab. Using the serial communications interface on the ATmegaP and MCJL16 microcontrollers – An explanation of the serial port and and how to use it to exchange data with other devices, along with examples of sending and receiving data over the ATmegaP and MCJL16 serial ports.

They may have absorbed Motorola’s TTL product line, or at least their tech library. Datashret of their files are scans of pages from their printed databooks and the images come out looking pretty bad. It’s usually easier to find parts in that catalog than online.

Texas Instruments – Datashee has a large collection of datasheets online, both for current chips and for many obsolete ones.

However they are still present in the our stock of parts so if you want to use them you can. Some functions may be missing or not functioning. Box ; Phoenix, Arizona All Electronics – This is basically a surplus store with both new and used components. If you are interested in purchasing electronic components for building datasheey, here are some links to places we buy parts from.

Motorola products are not designed, intended, or authorized for use as components in systems intended for surgical implant into the body, or other datasueet intended to support or sustain life, or for any other application in which the failure of the Motorola product could create a situation where personal injury or death may occur. We have no experience using the program at this time but it’s probably worth checking out.


However they do have a PDF of a pocket version of their logic data book. It will also get you on their mailing list for future catalogs.

Digi-Key – This is our other primary supplier. If 74ls221 have something you need, you can probably get it at a good price, but it’s sometimes hard to find things. They have a large inventory, the prices are reasonable, and we usually get the order pretty quickly.
