Application Scenarios & Design Considerations

Quadruple 2-Input Positive-AND Gates 14-SSOP

Alternative Part Number

  • MC74ACT08DR2G --: Quad 2-input AND gate with similar 74-series logic function and SOIC package, widely available as a direct functional substitute.
  • 74ACT08SC --: Quad 2-input AND gate in SOIC-14, compatible logic family and pinout for the SN74AS08DBR application.
  • CD74ACT08M --: Same manufacturer's ACT-family quad AND gate in SOIC, offering similar speed and drive characteristics as a cross-family alternative.
  • 74F08SJ --: Quad 2-input AND gate in the faster 74F family with similar propagation delay and pin-compatible SOIC package, suitable as a direct functional replacement.
