Working Principles

The SN74ALVCHS162830GR is a logic level translator that facilitates communication between integrated circuits operating at different voltage levels. It uses a combination of MOSFETs and CMOS technology to achieve bidirectional voltage translation.

The IC consists of multiple channels, each capable of translating signals from one voltage domain to another. The input voltage levels are shifted to the corresponding output voltage levels based on the supply voltage provided. This allows seamless integration of components operating at different voltage levels within a single system.
