Application Scenarios & Design Considerations

OCTAL D-TYPE FLIP FLOP WITH 3-STATE OUTPUT (NON INVERTING)

Alternative Part Number

  • SN74HC574N --: Pin-compatible octal D-type flip-flop with 3-state outputs from the widely available 74HC574 family; direct functional equivalent with different naming.
  • MC74HC574ADTR2G --: Same 74HC574 logic function and pinout, offered in SOIC package; well-stocked alternative with a distinct part number series.
  • CD74HC574E --: Equivalent octal D flip-flop with 3-state outputs, same HC logic family and pinout, suitable drop-in replacement.
  • MC74HC574ADWG --: Equivalent HC574 octal D flip-flop in SOIC package, widely available and functionally interchangeable.
