Application Scenarios & Design Considerations

Octal D-Type Flip-Flops With Clear

Alternative Part Number

  • MC74HC273ADTR2G --: Same HC-family octal D flip-flop with clear, TSSOP package, direct functional and pin-compatible replacement.
  • 74HC273PW,118 --: Equivalent octal D-type flip-flop with async clear in TSSOP, Pb-free and widely available.
  • CD74HC273M96 --: Same logic function from the same vendor family, though in SOIC package so footprint differs slightly.
