Semiconductor package is a carrier / shell used to contain and cover one or more semiconductor components or integrated circuits. The material of the shell can be metal, plastic, glass or ceramic.
The Maximum Operating Temperature is the maximum body temperature at which the thermistor is designed to operate for extended periods of time with acceptable stability of its electrical characteristics.
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.
