It acts as a line driver for buffering and driving heavily loaded backplane or memory bus traces. ## RoHS non-compliance — the one spec that decides fit The 74FCT240APC is marked RoHS non-compliant. The package finish contains lead (Pb) above the RoHS threshold — typically tin/lead solder dip on the through-hole leads. This part fits BOMs that have a RoHS exemption (e.g., high-rel, aerospace, or legacy industrial) or that are explicitly exempted from RoHS requirements. It does not fit new designs targeting full RoHS compliance without a waiver. Bulk packaging — tube or tray, not tape-and-reel — suits through-hole assembly lines and manual insertion. The DIP footprint is standard 0.300-inch wide, 20-pin, 0.100-inch pitch. ## Sourcing posture for an active, RoHS-legacy part Because the part is RoHS non-compliant, some distribution channels may carry limited stock or require a minimum order quantity.

This is typical for legacy through-hole logic parts with tin/lead solder. The part is suitable for BOMs with a RoHS exemption (military, aerospace, medical, or industrial maintenance) but cannot be used in new designs requiring full RoHS compliance without a waiver."},{"question":"Can the 74FCT240APC replace the SN74AHCT540DGVR on the same board?","answer":"No — the SN74AHCT540DGVR is a surface-mount (SSOP package) inverting buffer with a different pinout and footprint. The 74FCT240APC is a through-hole DIP part. They are not pin-compatible and require different PCB layouts. The FCT series also has different input thresholds and drive characteristics than the AHCT family."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/74FCT240APC","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/74FCT240APC when reusing this data.
