Application Scenarios & Design Considerations

FAST CMOS 8-BIT IDENTITY COMPARATOR

Alternative Part Number

  • CY74FCT521BTSOC --: Same FCT521B 8-bit identity comparator function with compatible pinout and speed grade; Cypress acquired IDT's FCT logic line, so this is a direct functional equivalent.
  • 74FCT521BTSO --: Renesas now owns the former IDT FCT logic portfolio; this part provides the same 8-bit identity comparator in the same SOIC package and speed grade.
  • SN74FCT521BTSO --: TI FCT521B series offers an equivalent 8-bit identity comparator with similar propagation delay and pin-compatible SOIC footprint, suitable as a second-source alternative.
