Working Principles

The CD4050BDW utilizes CMOS technology to achieve non-inverting logic level shifting. It consists of six independent buffers that can be used to convert logic levels from one voltage domain to another. Each buffer has an input and an output pin. When the input voltage is within the valid logic level range, the corresponding output will follow the input signal without any inversion. The wide supply voltage range allows the IC to operate with different power supply voltages.
