[sdiy] 4016 versus 4066 switches in MemoryMoog

[Tom Wiltshire]

Hi all,

I've been reading the MemoryMoog schematics, and I notice that in certain parts of the voice card they use 4016 analog switches (for example, turning osc waveforms on and off) but in other places they used 4066 analog switches (for example, voice modulation enables).

I've always regarded these two chips as broadly equivalent, but apparently Moog didn't think so. What's the important difference between them, and why use one rather than the other?

Thanks,
Tom
