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 ...

Logic level shifting may be required when interfacing legacy devices with newer devices that use a smaller geometry process. For bidirectional bus systems like the I2C-bus, such a level shifter must ...

When designing a system, one of the most important design decisions is choosing what voltage domain(s) to use. Some voltage domains, such as 5 V, are good for noisy and harsh operating environments ...
