The operating temperature is the range of ambient temperature within which a power supply, or any other electrical equipment, operate in. This ranges from a minimum operating temperature, to a peak or maximum operating temperature, outside which, the power supply may fail.
the distance between two baselines of lines of type. The word 'leading' originates from the strips of lead hand-typesetters used to use to space out lines of text evenly. The word leading has stuck, but essentially it's a typographer's term for line spacing.
The number of gates per IC varies depending on the number of inputs per gate. Two?input gates are common, but if only a single input is required, such as in the 744 NOT(or inverter) gates, a 14 pin IC can accommodate 6 (or Hex) gates.
