A modification to the DprobeXC in-circuit emulator enables engineers to record external transistor-transistor logic (TTL) signals, a requirement for testing integration for XC166 applications, says ...

Logic testers are simple but very helpful devices in testing digital circuits. A logic probe can be designed in many different ways. In this particular design, a combination of discrete and TTL logic ...

The circuits successfully performed the sum-of-product operation at 2.8 kHz. The full potential of memristors was demonstrated when the devices were made to actively re-program themselves.

SSRs that can be actuated with conventional CMOS and TTL logic-level voltages are available. SSR failure modes are primarily determined by the triac or SSR switching characteristics.

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 mac… ...

Engineers have created genetic circuits in bacterial cells that not only perform logic functions, but also remember the results, which are encoded in the cell's DNA and passed on for dozens of ...

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 ...

Taking advantage of DNA hybridization, we fabricated a series of nonarithmetic logic circuits on a simple and universal molecular beacon platform, including multiplexer, demultiplexer, encoder and ...
