Working Principles

The IDT74LVCH162245APVG is a bidirectional voltage level translator that allows seamless communication between two different voltage domains. It uses a combination of level shifters and direction control circuitry to ensure proper translation of logic levels.

When data is transmitted from Port A to Port B, the direction control circuitry automatically sets the direction to translate the voltage levels from the lower voltage domain (Port A) to the higher voltage domain (Port B). Conversely, when data is transmitted from Port B to Port A, the direction control circuitry adjusts the translation direction accordingly.

The level shifters within the IC ensure that the logic high and low levels of the input signals are properly translated to the corresponding voltage levels of the output signals, allowing for seamless communication between different logic families.
