Working Principles

The BUF08821AIPWPR is a voltage-level translator that uses a combination of MOSFETs and level-shifting circuitry to convert signals between different logic levels. It operates by monitoring the input logic levels and translating them to the corresponding output logic levels based on the specified voltage thresholds.

When an input signal is received, the IC determines the logic level and translates it to the desired output logic level. The output enable pin (OE) can be used to enable or disable the translation function.
