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.
