Application Scenarios & Design Considerations

Dual 4-Bit D-Type Latches With 3-State Outputs

Alternative Part Number

  • 74ALS873BDWR --: Same 74ALS873 function (dual 4-bit D latch) in the same wide-body SOIC-20 package, offered by an alternate logic vendor for second-source supply.
  • SN74ALS873BNT --: Identical ALS873 dual 4-bit latch from TI in a PDIP-20 through-hole package, suitable when board layout allows a through-hole footprint.
  • MC74ACT873DWR2 --: Functionally equivalent octal/dual 4-bit D latch in a similar wide SOIC-20 package; ACT family offers comparable speed with CMOS-compatible inputs.
