Before the era of large-scale integration (LSI) semiconductor circuits, discrete logic circuits using the common diode-transistor logic (DTL) were still necessary and available in a format that was ...

The previous article examined the concept of logic gates. They can be made from discrete and active electronic components, although today logic gates are available within integrated circuits. In this ...

As we have observed in previous parts of this course, in a digital system, signals can take on only two values: high or low. These values are often represented by two voltage levels. The most used ...

March 29, 1961 - LOGICAL microcircuits in transistor cans are now being offered by four major companies. Heavy research and production is being pressed by Fairchild Semiconductor Corp., Raytheon Co., ...
