Application Scenarios & Design Considerations

Octal D-Type Edge Triggered Flip-Flops with 3-State Outputs

Alternative Part Number

  • 74F374PC --: Octal D-type flip-flop with tri-state outputs, functionally equivalent to the AS374 and pin-compatible in DIP-20; faster F-series logic is a common drop-in replacement.
  • MC74ACT374N --: Octal D flip-flop with 3-state outputs in DIP-20, CMOS ACT family offers similar speed and direct logic-level compatibility for the AS374 function.
  • CD74HCT374E --: HCT octal D-type flip-flop with tri-state outputs in DIP-20, same manufacturer and pinout, suitable when slightly lower speed is acceptable.
