The tester itself is relatively simple ... the NPN/PNP pair causes the LED to light up, but the circuit is broken whenever one of the transistors is removed. Inserting a new transistor into ...

Avoid power leaks, power-ground DC paths, and missing level shifters with symbolic simulation. Nothing is worse for a design ...

or instant response—do you feel is the most important for transistors used in computers? in medical equipment such as pacemakers? in guided missiles? Use your circuit to test how well other ...

For example, you can insert a resistor, a capacitor, an inductor, a diode, or a transistor and get a readout of which pin is which. It seems like magic, but [Andreas Spiess] did the research on ...

As with many inventions, two people had the idea for an integrated circuit at almost the same time. Transistors had become commonplace in everything from radios to phones to computers, and now ...

Philco is expected to be in production shortly on preliminary transistor-diode “logic pacs.” Sperry Semiconductor Div. is in pilot production on Semi-Net NOR circuits in TO-5 cases.
