Versatile Logic System for Use in Nuclear Experiments on Scientific Satellites

An improved fast low-power-drain logic system has been developed for use in nuclear experiments on scientific satellites. The basic unit of the system is an AND-NAND gate which has a response in the 10 nanosecond range, a power drain of 2.0 milliwatts and operates over the temperature range of -40°C to +80°C. In addition to providing the AND-NAND logic functions, one or more of the basic units may be connected to yield the following: a. monostable pulse generator, b. pulse generator yielding an output pulse at the leading edge of the input pulse, c. Delay, d. Threshold Detector, and e. Bistable Circuit. The system requires relatively simple circuitry for interfacing at its outputs and inputs.
