bidirectional switches that can switch analog or digital, even video signals. The 4051 is a 1-of-8 switch, the 4052 is a 2-of-4 switch (great for stereo), and the 4053 is a triple 1-of-2 switch. Pinouts can be found by Google or any Motorola/Fairchild data book. A good reference to these devices is the CMOS Cookbook by Don

I'm trying to build an audio switch with a 74HC4051 multiplexer an looking for ideas/schematics about ways to reduce disturbance (click etc) on the output. I have six radio channels on the input and a PI gives signals which input to activate. I know the 4051 isn' considered very good in hi-fi sound but I want it cheap and will tr
