This volume emphasizes analytical reasoning skills and basic digital design using industry-standard ICs. It teaches the practical skills students need to design and troubleshoot the digital circuitry they will face at work. The author uses actual industry integrated circuits to demonstrate circuit operations, and a solid step-by-step progression is made from fundamentals through more complicated topics. Emphasis is on the basics of circuit design, so that students, knowing the foundational building blocks, can then teach themselves new technology as it appears. In this edition new sections on surface mounted devices and on low-voltage (74LV) integrated circuits acquaint students with current technology while several new circuit operational notes are provided in the text figures.
