Application Scenarios & Design Considerations

FAST CMOS QUAD 2-INPUT MULTIPLEXER

Alternative Part Number

  • CY74FCT2257CTQ --: Same FCT2257 function (quad 2-input multiplexer with 25-ohm series resistors) in the same QSOP package, from the vendor that acquired IDT's FCT logic line, so pinout and specs match closely.
  • 74FCT2257CTQ --: Renesas offers the standard 74FCT2257 function with 25-ohm output resistors in QSOP, providing a direct functional and package-compatible replacement.
  • PI74FCT2257TQ --: Pericom/Diodes FCT2257 series quad multiplexer with series damping resistors in QSOP package, electrically equivalent and widely available as a second source.
