In digital circuits, a logic level is one of a finite number of states that a signal can have. Logic levels are usually represented by the voltage difference between the signal and ground (or some ...

In the first installment of this course, we learned that a digital value is a quantity that varies “in steps” and can take on only a finite number of values. In today’s logic systems, only two ...

Diodes has automotive qualified a four-bit bidirectional level translator that does not require a direction control pin. Its B and A ports are designed to track two different power supply rails (VccB ...

Toshiba is aiming at UART and SPI interfaces with three four-channel dual-supply level-translator-transceivers. “The bus transceivers support level-up and level-down voltage translation from either of ...

Last time, we’ve used a logic analyzer to investigate the ID_SD and ID_SC pins on a Raspberry Pi, which turned out to be regular I2C, and then we hacked hotplug into the Raspberry Pi camera code with ...

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, ...
