It handles bidirectional data flow between two buses, a function needed in memory interfaces, backplane drivers, and multi-master systems where direction control and bus isolation matter. The FCT family is known for its TTL-compatible input thresholds and low static power, making it a drop-in for legacy 5 V TTL backplanes while drawing CMOS-level supply current. ## RoHS non-compliant — flag for lead-free lines This part is RoHS non-compliant. That means it contains lead (Pb) above the 0.1% threshold — typically in the solder finish or die-attach. If your assembly line is RoHS-only with lead-free solder and no exemption, this part cannot run through it without a waiver. For military, aerospace, or medical equipment that still uses tin-lead solder per exemption, the non-compliant status is not a blocker and may even be preferred for reliability in high-vibration or thermal-cycling environments. ## Package — Bulk form factor That matters for the production floor: Bulk parts need hand-loading or tube feeders; they won't run on a standard SMT pick-and-place without a tray or tube feeder setup. For prototyping, rework, or low-volume builds, Bulk is often more convenient than cutting a reel.","metaTitle":"CY74FCT2543TQC Bus Transceiver, FCT Series, Active","metaDescription":"CY74FCT2543TQC bus transceiver from the FCT series.
