IC Series - Episode 01 - D-Type Flip-Flop (74ABT821D)

I bought a bag of integrated circuits (IC) from eBay -- it is about 1/2 a pounds and contains all kids of TTL, CMOS, Semiconductors, etc. And the "etc" is very interesting.

I'm going to go through as many of them as I can and put them on a breadboard, review the datasheet, build up a test circuit, write some Arduino code, and see what I can make them do.

Some of these I will also hook up to my oscilloscope and give them a few tests.

In this video, I cover a Philips 74ABT821D, 10-bit D-type flip-flop with a positive-edge trigger.

I'm doing this because I love to learn new things and find old ICs fascinating. While these ICs may not be practical anymore with our microcontrollers, it is still a lot of fun to learn how they work, what they were used for, and what we might be able to use them for in the future. ... https://www.youtube.com/watch?v=G_vzbE9twcg
