Application Scenarios & Design Considerations

DUAL 16-BY-4 REGISTER FILES

Alternative Part Number

  • 74ALS870D --: Same 74ALS870 function in a different vendor's DIP/SO naming scheme, electrically equivalent and widely available as a second source.
  • SN74ALS870NT --: Same TI ALS870 die in a PDIP package, useful when the SOIC DW footprint is not required and a through-hole option is acceptable.
  • 74ALS870DW --: Equivalent ALS870 device from an alternate manufacturer in the same SOIC wide-body package, providing supply-chain redundancy.
