Working Principles

The MC74VHC4052DR2 operates based on the principle of analog multiplexing. It uses a combination of control signals (S0-S3) to select one of the eight input/output channels. The INHIBIT (INH) and Common Enable (EN) pins control the overall operation of the device. When the appropriate control signals are applied, the selected channel connects the input signal to the output pin, allowing the signal to pass through. The device operates within the specified supply voltage range and provides low on-state resistance and fast switching times.
