Modern TTL Circuits

Modern high-speed digital electronics is dominated by two basic logic technologies: transistor-transistor logic (TTL) and complementary MOSFET logic (CMOS). This circuits manual takes an in-depth look at the leading high-speed general purpose range of digital ICs, the 74 series. Over 360 useful and proven circuits, diagrams, graphs and tables are explained with all the information needed to show how TTL works, and how to use this key technology. The manual is split into seven chapters. First the basics of digital ICs are explained, followed by the principles of TTL technology. Practical details of the 74 family of ICs, including the latest sub-families, and the TTL basic-usage rules, are then explored. Modern logic circuitry (including the symbology and mathematics of digital logic) is explained in chapter two, along with a wealth of practical logic circuitry and data. The following chapters deal with waveform generator circuitry, clocked flip-flop and counter circuits, special counter/dividers, data latches, registers, comparators, and code converters. This book should be of interest to circuit designers, technicians, students and experimenters.
