Application Scenarios & Design Considerations

Serial-out shift registers with input latches

Alternative Part Number

  • CD74HC597M --: Same 16-pin SOIC shift register with parallel input and serial output; HC family offers similar function with different prefix for easy distinction.
  • MC74HC597ADG --: Pin-compatible 8-bit shift register with input latch in SOIC-16, direct functional replacement from a different manufacturer and series.
  • 74HC597D,653 --: Equivalent 8-bit parallel-in/serial-out shift register in SOIC-16 package, widely available alternative with different naming.
