On the path to exploring complex logic, let’s discuss the electrical properties that digital logic signals are comprised of. While there are many types of digital signals, here we are talking about ...

Somehow, though, that doesn’t seem as much fun as virtually connecting 7400 chips together. Don’t ask us why. There’s also a link to an impressive open source web-based logic simulator. You can grab ...

Transistor-Transistor Logic (TTL) Logic Decoders and Demultiplexers are digital circuits used to convert binary information from input lines to unique output lines. A decoder is a combinational ...

This document tackles the basic facts of the 74HCT TTL Compatible CMOS components. It includes a comparison between its sub-family of components. Suggestions on what CMOS to use on a specific ...

TTL (Transistor-Transistor Logic) logic counters are digital devices used to count the number of occurrences of an event. They are constructed using TTL technology, which employs bipolar junction ...

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 ...

I have noticed this and it finally bugs me enough that I want to ask. In digital and embedded systems, why is the reset signal always negative logic? Is there a reason why almost everyone uses ...

How to get hands-on with logic gates without soldering. Using the SmartSim simulator, the hardware becomes software and you can avoid burnt fingers and burned components. So let's get started. Logic ...

Timing relationships between signals are critical to reliable operation of digital designs. With synchronous designs, the timing of the clock signal relative to data signals is especially important.
