Disadvantages: - Limited number of channels (4) - Relatively small package size

Working Principles

The SN74CBT3305CDGKR utilizes analog switch technology to route signals between input channels and the output. The channel select inputs (A0 and A1) determine which input channel is connected to the output. When the output enable input (OE) is high, the selected channel's signal is passed through to the output. Conversely, when OE is low, all channels are disconnected from the output.
