This device is commonly used in digital logic applications requiring NOR gate functionality.

Application Scenarios & Design Considerations

Quadruple Positive-NOR Gates With Schmitt-Trigger Inputs

Alternative Part Number

  • MC74HC7002DG --: Same HC7002 quad NOR gate with Schmitt-trigger inputs in SOIC-14, direct functional and pin-compatible replacement.
  • CD74HC7002E --: TI's own HC7002 series part with identical logic function and Schmitt-trigger inputs, though in PDIP package rather than SOIC.
  • 74HC7002D,653 --: HC7002 quad Schmitt-trigger NOR gate in SOIC-14, same logic family and function, suitable drop-in alternative.
