Level shifters translate logic voltages between devices so controllers, sensors and peripheral modules can communicate reliably without damaging interfaces. They are used in serial buses, GPIO interfacing, sensor integration and mixed-voltage boards where signal integrity and proper logic thresholds matter.
Products range from simple single‑direction level translators to bi‑directional, automatic direction sensing devices, and opto‑isolators that provide galvanic isolation for high‑voltage or noisy systems. Key attributes include supported voltage ranges, channel count, data‑rate capability, input/output drive style and ease of integration via breakout wiring or solder pads. Reliability, predictable timing and compatibility with common buses are central to real‑world use.
