Working Principles

The CLVTH16652IDGGREP utilizes a combination of MOSFETs and level-shifting circuits to achieve bidirectional voltage translation. The device automatically senses the direction of data flow and adjusts the voltage levels accordingly. When translating from a lower voltage domain (A Port) to a higher voltage domain (B Port), the device uses level-shifting circuits to boost the logic levels. Conversely, when translating from a higher voltage domain to a lower voltage domain, the device employs MOSFETs to safely lower the voltage levels.
