Working Principles

The SN74LVTH16952DLR utilizes a combination of MOSFETs and CMOS technology to achieve voltage level translation. The direction of data flow is controlled by the DIR pin. When DIR is high, data is transferred from Port A to Port B, and when DIR is low, data flows in the opposite direction.

The IC incorporates level-shifting circuitry that ensures proper logic level conversion between the input and output pins. This allows seamless communication between devices operating at different voltage levels.
