The circuit above is a 3−input Diode−Transistor Logic (DTL) gate. Write the truth table for the input combinations of 0 V and 5 V with respect to the ground. Which type of logic gate does this circuit ...

The familiar five volts standard from back in the TTL days always struck me as odd. Back when I was just a poor kid trying to ...

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 ...

The four-layer diode was the key to William Shockley's plan to revolutionize AT&T's phone system. It was a great device in theory, but not in practice -- at least not at the time when Shockley wanted ...

‘Commenting upon the apparently universal adoption of ferrite-core storage and transistor-based logic in contemporary computers, the science correspondent of a Sunday newspaper recently concluded that ...

Here’s a blast from the past as we reprint our news from NYC’s 1961 IRE show—the first integrated logic circuits in TO-5 and TO-18 cans are being announced. March 29, 1961 - LOGICAL microcircuits in ...

Claimed as the industry's first optocouplers directly compatible with today's 3.3V low-power microcomputer chips and logic families, this new line of optocouplers eliminates the need for an additional ...

Before the era of large-scale integration (LSI) semiconductor circuits, discrete logic circuits using the common diode-transistor logic (DTL) were still necessary and available in a format that was ...
