Working Principles

The SN74CBTLV16211DL is a logic level translator that facilitates communication between devices operating at different voltage levels. It uses channel select inputs (S0-S7) to determine the desired data path and voltage translation control inputs (VT0-VT7) to set the voltage translation direction.

When the enable inputs (E0-E7) are activated, the corresponding data inputs/outputs (D0-D15) are connected to the bidirectional voltage translation circuitry. The output enable inputs (OE0-OE7) control the state of the outputs, allowing them to be enabled or disabled as needed.

The IC's internal circuitry ensures low on-state resistance, minimizing signal distortion during voltage translation. This enables reliable and efficient data transfer between devices operating at different voltage levels.
