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 ...

A flip-flop is one of the most basic digital electronic circuits. It can most easily be built from just two transistors, although they can and have been built out of vacuum tubes, NAND and NOR gates, ...

A variety of logic-circuit techniques have been in use since the 1960s, when integrated logic first came into existence. In the beginning was Resistor-Transistor Logic (RTL). Then came ...

From simple transistors to complex systems, this article explains the building blocks of digital logic design. Learn how ...

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 ...

‘Commenting upon the apparently universal adoption of ferrite-core storage and transistor-based logic in contemporary computers, the science correspondent of a Sunday newspaper recently concluded that ...

Description: Analysis and design of digital electronic circuits. Resistor logic; diode logic; direct coupled transistor logic; resistor-transistor logic (RTL); diode-transistor logic (ETL); transistor ...

Here’s a blast from the past as we reprint our news from NYC’s 1961 IRE show—the first integrated logic circuits in TO-5 and TO-18 cans are being announced. March 29, 1961 - LOGICAL microcircuits in ...
