Application Scenarios & Design Considerations

Quadruple 1-of-2 Data Selectors/Multiplexers

Alternative Part Number

  • 74ALS158N --: Same 74ALS158 quad 2-to-1 multiplexer function with active-low outputs in a DIP-16 package, pin-compatible with the TI device.
  • DM74ALS158N --: Direct equivalent ALS158 multiplexer in DIP-16, same logic family and pinout, suitable drop-in replacement.
  • SN74LS158N --: LS-family quad 2-to-1 multiplexer with identical pinout and function; slightly higher power but widely available as a fallback.
