Working Principles

The SN74HC125APWR operates based on CMOS (Complementary Metal-Oxide-Semiconductor) technology. It utilizes a combination of NMOS (N-channel Metal-Oxide-Semiconductor) and PMOS (P-channel Metal-Oxide-Semiconductor) transistors to achieve non-inverting logic level translation. When the input signal is high, the corresponding output is also high, and vice versa. The output enable control allows the user to enable or disable the outputs as needed.
