Clocked Flip-flops
Most digital ICs are based on either simple logic gate networks of the types described in earlier chapters, or on clocked bistable or flip-flop elements. This second type includes simple counter/divider ICs, shift registers, data latches, and complex ICs such as presettable up/down counters and dividers. The present chapter explains how clocked flip-flop circuits work, and presents practical user information on some popular clocked flip-flop and counter/divider ICs. As an immediate follow-up, Chapters 11 and 12 look at advanced counter/divider ICs and various associated devices.
Clocked Flip-flop Basics
The simplest type of flip-flop is the cross-coupled bistable, which has already been briefly described in Chapter 8
