Working Principles

The CD4049UB is based on CMOS technology, which allows it to operate at a wide range of supply voltages while consuming low power. It consists of six individual inverters/buffers, each with its own input and output. The inputs are capable of accepting high voltage signals, making the IC suitable for various applications.

When an input signal is applied, the corresponding inverter/buffer produces the inverted output signal. The propagation delay, although minimal, should be considered in timing-sensitive applications. The IC requires a positive power supply (VDD) and a negative power supply (VSS) for proper operation.
