Application Scenarios & Design Considerations

Quadruple 2-Input Positive-NOR Gates

Alternative Part Number

  • MC74HC02ADTR2G --: Quad 2-input NOR gate in HC logic family with equivalent function and TSSOP-14 package, direct drop-in replacement.
  • 74HC02PW,118 --: Same quad 2-input NOR gate HC logic in TSSOP-14, pin-compatible and widely available alternative.
  • CD74HC02M96 --: Same manufacturer HC-family quad NOR gate with matching electrical characteristics, though in SOIC-14 package requiring footprint check.
  • 74HC02D --: Quad 2-input NOR gate in SOIC-14, same HC logic family and function, widely available and pin-compatible in a similar package.
  • MC74HC02ADR2G --: Quad 2-input NOR gate with HC speed, SOIC-14 package, direct functional equivalent with good availability.
  • CD74HC02E --: Same manufacturer HC-series quad NOR gate, though in DIP package, useful as a drop-in functional substitute when package constraints allow.
