Working Principles

The 74LVC827AD,118 is based on CMOS (Complementary Metal-Oxide-Semiconductor) technology. It utilizes a combination of MOSFETs (Metal-Oxide-Semiconductor Field-Effect Transistors) to perform the voltage level translation. The direction of data flow is automatically controlled based on the input and output voltage levels. When the input voltage is higher than the output voltage, the IC acts as a logic level shifter, translating the high-level signals to the lower level. Conversely, when the input voltage is lower than the output voltage, the IC performs the opposite translation.
