Working Principles

The PI5A121CE is an analog switch that operates by controlling the flow of signals between its input and output channels. When a specific input control pin is activated, the corresponding channel connects the input to the output, allowing the signal to pass through. The switch's low on-resistance ensures minimal signal attenuation, while the low off-leakage current prevents unwanted signal leakage.
