Description: This line of M.S.I. SUHL devices was originally introduced by Sylvania. These devices are completely compatible with the TTL I and II families of SUHL devices.

I saw a request about how to interface an audio signal with a microcontroller for logic level switching. I started thinking a lot about it and found some quick fixes. This post has my ramblings about ...

Pity the poor TTL computer aficionado. It’s an obsession, really — using discrete logic chips to scratch-build a computer that would probably compare unfavorably to an 80s era 8-bit machine in terms ...

As we have observed in previous parts of this course, in a digital system, signals can take on only two values: high or low. These values are often represented by two voltage levels. The most used ...
