This is still an essential guidebook in so many ways.
Here's one:
>Many classes of circuits are neither entirely analog nor entirely digital.
>when problems develop in circuits containing both analog and digital elements, finding a solution is more likely to require that you summon your analog expertise than your digital knowledge.
>Digital ICs have more than a few analog subtleties. And even multiplexers, which you may have thought of as purely analog, have some quirks that result from their close association with the digital world.
