The purpose of a circuit diagram is to convey the maximum amount of information in the most efficient fashion. One aspect of this is assigning meaningful names to wires; for example, naming a wire ...

If your introduction to digital electronics came more years ago than you’d care to mention, the chances are you did so with 5V TTL logic. Above 2V but usually pretty close to 5V is a logic 1, below ...

There is one thing that unites almost every computer and logic circuit commonly used in the hardware hacking and experimentation arena. No matter what its age, speed, or internal configuration, ...

In electronic design, a level translator enables communication between devices whose I/O voltages don’t match. Years ago, the I/O voltages usually matched, because most processor and logic devices ...
