In the early digital era, logic gates were made exclusively of transistors and discrete components. The obvious occupation of a large space and increased heat dissipation pushed technology to ...

DigiSim is a simple simulator for TTL circuits to display the timing behavior similar to a logic analyzer. The GUI looks familiar to anyone programming and simulating Xilinx FPGAs. DigiSim that can ...

Self-acclaimed computer nerd [Kevin Koster] was tired of designing new TTL-logic clocks before finishing his previous designs. So he finally buckled down and completed this unique word clock, which ...

Diodes has introduced a range of logic devices intended as a performance upgrade for legacy 5V TTL systems. Based on an advanced CMOS process, the 74AHCT1Gxx devices serve as TTL compatible drop-in ...

This Design Idea describes a new class of logic gates, which we have named resistor-FET-logic, aka “RFL.” How do we know it is new? While FET switches are common today, we have been unable to find a ...

In a proof-of-concept study, researchers have created self-assembled, protein-based circuits that can perform simple logic functions. The work demonstrates that it is possible to create stable digital ...

Cells of all organisms process numerous signals originating from the internal biological processes or from the environment to produce the appropriate cellular response. Designed gene regulatory ...
