Drawing from an earlier Design Idea (Reference 1) and a recent design requirement for adding pulse-generation functions to a crowded pc board, I searched Fairchild Semiconductor's Web site ...

In this article, however, other logic gates are examined ... The small circle placed on the output of the gate indicates its inverting functionality of the logic signal. The gate can also provide more ...

Unused multi-input gates. The next level in our meandering musings is to decide what to do with unused multi-input gates. Let’s start with 2-input AND and OR gates as an example. Assuming we are all ...

Most logic synthesis algorithms work on graph representations of logic functions with nodes associated with arbitrary logic expressions or simple logic functions and iteratively optimize such graphs.

There are, on the market, integrated circuits that implement AND logic gates with two, three, four or more inputs. If need be, the designer can appropriately connect several AND logic gates to ...

Unused single-input gates. Let’s start with unused single-input gates, such as NOT (inverter) and BUF (buffer) functions. Without specifying a particular implementation technology at this stage, let’s ...
