Working Principles

The CLVTH162245IDGGREP is designed to facilitate the translation of logic signals between two different voltage levels. It operates by automatically detecting the direction of data flow based on the DIR (Direction) control inputs. When a logic HIGH is applied to the DIR input corresponding to Channel A, the device translates signals from the A port to the B port. Conversely, when a logic LOW is applied to the DIR input, the translation occurs in the opposite direction.

The integrated circuit utilizes a combination of MOSFETs and level-shifting circuitry to achieve bidirectional voltage translation while maintaining signal integrity and minimizing propagation delay.
