Application Scenarios & Design Considerations

Quad R-S Latches

Alternative Part Number

  • CD4043BM96 --: Pin-compatible CMOS quad R/S latch in the same 4000-series family, widely available and a direct functional drop-in for the MC14043.
  • HEF4043BT,653 --: Quad R/S latch with equivalent logic function and pinout, offering a different manufacturer and series prefix for easy distinction.
  • MC74HC4043ADG --: HC-series quad R/S latch from the same vendor with similar function; note it is a faster HC variant, so verify supply voltage and timing compatibility.
