Application Scenarios & Design Considerations

Quad Latch

Alternative Part Number

  • CD4042BE --: Pin-compatible CMOS quad D-latch equivalent to the MC14042B, widely available and directly interchangeable in most designs.
  • HEF4042BP --: Standard 4000-series quad D-latch with the same function and pinout, suitable as a direct functional replacement.
  • MC74HC4042AD --: HC-series quad D-latch from the same family with similar logic function and compatible pinout, offering improved speed characteristics.
  • MC14042BCP --: Same 4000-series quad D-latch function from the successor brand of the original manufacturer, suitable as a drop-in replacement.
