Application Scenarios & Design Considerations

Octal Edge-Triggered D-Type Flip-Flop With 3-State Outputs

Alternative Part Number

  • MC74LCX574DTG --: Octal D-type flip-flop with 3-state outputs in the LCX family, functionally equivalent to the LVC574A with similar 2.3-3.6V operating range and pin-compatible TSSOP package.
  • 74LVC574APW --: Direct functional equivalent octal D flip-flop with 3-state outputs from Nexperia's LVC logic family, same 2.0-3.6V supply and TSSOP-20 footprint.
  • SN74AHC574PWR --: Octal D-type edge-triggered flip-flop with 3-state outputs in AHC family, pin-compatible TSSOP-20 alternative when slightly different speed and 2-5.5V supply range are acceptable.
