ECL circuits typically have relatively small logic spans of approximately 800 mV. Because of the small span, to drive TTL circuits from ECL levels normally entails the use of level converters, such as ...

The logic on-off function allows the user to shut off the converter’s output using a simple TTL logic signal or mechanical switch, and avoids having to turn off the DC input bus. This feature is ...

Since 1972, scientists have known there are four basic circuit components, but if you’ve spent any time in an electrical engineering classroom, you probably only have experience with three: capacitor, ...

There is one thing that unites almost every computer and logic circuit commonly used in the hardware hacking and experimentation arena. No matter what its age, speed, or internal configuration, ...

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 ...

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 ...

Living cells make decisions based on information processing genetic programmes. Many of these programmes execute digital functions 1,2,3,4,5,6,7,8. The capability to build synthetic digital systems in ...

Non-volatile bistable memory circuits pave the way for highly energy-efficient CMOS logic systems. Non-volatile bistable memory circuits being developed by Satoshi Sugahara and his team at Tokyo Tech ...

Pity the poor TTL computer aficionado. It’s an obsession, really — using discrete logic chips to scratch-build a computer that would probably compare unfavorably to an 80s era 8-bit machine in terms ...
