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 ...

5V to 3.3V level translation. For either direction (auto-detection). No need for I/O Off feature (both sides are powered-up at the same time). Bus Switch is always on. Bus Switch should pass digital ...

We are using the part PCA9306DCUR to level translate from 3.3V to 5V I2C interface. The flow is as shown below. We are able to read the I2C address of the fan controller device but when we try to read ...

The SparkFun Single Supply Logic Level Converter is logic level and power supply translator in one small package. This little board breaks out the Texas Instruments TXB0104 4-bit bi-directional ...

Two NVT2010PW ICs are available on a single board, to either level shift from 3.3V to 5V or from 3.3V to 1.8V and 1.2V (jumper selectable). The RPi's 5V is used for the 5V level shift and two on-board ...

Interfacing a 1.8V microcontroller to a 3V peripheral poses a design challenge ... the voltage at active-low SHDN rises to 2.5V and the MAX9718 is able to turn on. Figure 1. Simple level translator.

A related application for the five comparators of IC1 is to translate the logic signals generated by 3V devices to the levels appropriate for 5V devices.
