As digital devices get smaller and faster, 5V logic has given way to lower-voltage standards like 3.3V, 2.5V, and even 1.8V, leading to a need for help when components that operate at different voltages have to communicate with one another. For example, a 5V device might fail to read a 3.3V signal as high, and conversely, a 3.3V device might be damaged by reading a 5V signal. The level shifter in this listing solves these problems by offering bi-directional voltage translation of up to four independent signals, and its compact size and breadboard-compatible pin spacing make it easy to integrate into projects.
An important feature of this logic level converter is that they’re bi-directional, which means that it can transmit data from high to low and/or low to high on all channels. It’s perfect for level-shifting between devices that are sharing a data wire, like I2C or a one-wire interface.
As with all of our Boards the pin headers are included, but they’re not soldered in to allow for different use cases!
- The lower-voltage supply can be 1.2~3.6VDC whereas the higher-voltage supply can be 1.65~5.5VDC
- Four independent, bi-directional channels are available
- Size: 28mm × 19mm (1.10″ × 0.75″ (L×W))
- 10-Pin header included (soldering needed!)
