Application Scenarios & Design Considerations

Octal D-Type Flip-Flops With Clear

Alternative Part Number

  • CD74HCT273M --: HCT-family octal D flip-flop with clear, same 20-pin SOIC function and TTL-compatible inputs, direct functional replacement.
  • MC74HC273ADWR2G --: HC-family octal D flip-flop with clear in SOIC-20, widely available and pin-compatible with the LS273 function.
  • 74ACT273SC --: ACT-family octal D flip-flop with clear, TTL-level inputs and higher speed, suitable drop-in functional alternative.
  • MC74ACT273DWR2G --: ACT-family octal D flip-flop with clear in a 20-pin SOIC wide-body package, functionally equivalent and TTL-input compatible.
  • 74F273PC --: Faster bipolar octal D flip-flop with clear, same logic function and pinout, usable where higher speed is acceptable.
