EEVblog #1208 - Circuit Analysis & Debugging
Fundamentals Friday
Dave answers a beginner forum question of why their 74HC390 based breadboard counter circuit does not work properly.
Let's get up to our armpits in datasheets and troubleshooting.
A two sentence forum response turned into a step-by-step 27min video investigation involving rise and fall times, setup and hold times, metatability, optocouplers, bypassing, open collectors, and breadboard connector traps for young players.
