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 ...

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 ...

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 ...

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, ...

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 ...

Solid-state relays are much smaller than corresponding single-pole relays. They are also faster, dissipate less power, and withstand a larger number of operations. And unlike electromechanical relays, ...

Fig 1. A typical CMOS input circuit comprises a “P” and “N” transistor. One is fully “on” for logic high, and the other is “on” for a logic low. Fig 2. When a CMOS input pin is at logic high or low ...
