Transistor NOR circuit design
William D. Rowe, George H. Royer · Transactions of the American Institute of Electrical Engineers Part I Communication and Electronics · 1957
THE transistor NOR circuit was introduced because of the desire to have a single logic element which would combine well in logic configurations with a minimum of concern for matching and element loading. A NOR element has a signal output only if there are no input signals, and consequently has no output if any input signal is present. Such a single logic element must have a considerable amount of flexibility to meet the various input and output loadings, operating temperatures, and power-supply variations which may be encountered. This paper considers the circuit design of the transistor NOR circuit.
