Switching Theory
https://www.electronics-lab.com/article/switching-theory/
Switching Theory The switching theory uses switches in order to understand the operation and functioning of digital logic gates and circuits. The switching theory helps in developing better theoretical knowledge and concepts of digital logic circuits involving logical inputs producing a specific relational logical output. As it has already been discussed that Boolean data type […]
Universal Logic Gates
https://www.electronics-lab.com/article/universal-logic-gates/
Universal Logic Gates The NAND and NOR logical gates are most commonly termed as Universal Logic Gates as they can be used to construct all other logical functions and Boolean expressions. As it is learned from previous articles that AND, OR, and NOT are the most basic type of logic gates. They are the most […]
Logic AND Gate
https://www.electronics-lab.com/article/logic-and-gate/
Logic AND Gate We know from the Digital Logic Gates Introduction that a digital circuit at its input and output can have only two – states i.e. either “HIGH” or “LOW”. The logic “HIGH” and “LOW” are also termed as “1” and “0” logic, respectively. The voltage level at the input or output is the determinant […]
Digital Logic Gates Introduction
https://www.electronics-lab.com/article/digital-logic-gates-introduction/
Introduction In short, a digital logic gate is a description of a device or circuit that can make a logical decision and has a set of known outputs based on the combination of input signals. These logic gates can have any number of inputs, often labeled as letters starting at A (so a 2 input […]
Inside the 74181 ALU chip: die photos and reverse engineering
https://www.electronics-lab.com/inside-74181-alu-chip-die-photos-reverse-engineering/
A detailed die photos and reverse engineering of the 74181 ALU chip by Ken Shirriff: What’s inside a TTL chip? To find out, I opened up a 74181 ALU chip, took high-resolution die photos, and reverse-engineered the chip.1 Inside I found several types of gates, implemented with interesting circuitry and unusual transistors. The 74181 was a […]
