Working Principles

The SN74ALVC16835ZQLR is a voltage-level translator that enables communication between two logic circuits operating at different voltage levels. It utilizes a combination of MOSFETs and level-shifting techniques to convert signals from one voltage domain to another.

When an input signal is applied to the A-side of the IC, it undergoes level shifting and is then transmitted to the corresponding output port on the B-side. Similarly, signals applied to the B-side are translated and sent to the appropriate output port on the A-side.

The IC also features output enable inputs (OE1-OE8) that control the direction of data flow. When the OE input is low, the outputs are enabled and data can be transmitted bidirectionally. Conversely, when the OE input is high, the outputs are disabled, preventing any data transfer.
