Application Scenarios & Design Considerations

Octal D-Type Transparent Read-Back Latches With 3-State Outputs

Alternative Part Number

  • 74ALS666DW --: Same 74ALS666 octal transparent D-type latch function in a 24-pin SOIC-wide package, pin-compatible with the TI device.
  • DM74ALS666WM --: Equivalent ALS-series octal latch with 3-state outputs in a wide SOIC package, a direct functional and package match.
  • SN74ALS666NT --: Same TI ALS666 die in a 24-pin PDIP package; electrically identical, suitable when through-hole mounting is acceptable.
