Working Principles

The SN74LVTH16240DLRG4 operates by receiving input signals from one voltage domain and translating them to the corresponding logic levels of another voltage domain. It utilizes a combination of MOSFETs and CMOS technology to achieve this level translation while maintaining high-speed operation and low power consumption.

The direction control pin (DIR) determines the direction of translation. When DIR is set to logic high, the inputs are translated to the outputs in one direction, and when DIR is set to logic low, the translation occurs in the opposite direction.
