Rated for a 4.75V to 5.25V supply, this part expects a regulated 5V rail with ±5% tolerance. The 32mA high-level and 64mA low-level output currents give it the headroom to switch the capacitance of a long trace or multiple loads on a single bus segment — but the asymmetric drive (64mA low, 32mA high) means the falling edge is faster than the rising edge, something to account for in signal-integrity budgeting on high-speed lines. The 1.27 mm pitch is standard for this footprint. ROHS3 compliant, so it passes current European and global restriction-of-hazardous-substances requirements without issue.","metaTitle":"CY74FCT240ATSOC 74FCT Inverting Buffer, 32mA/64mA, 20-SOIC","metaDescription":"CY74FCT240ATSOC from TI, 74FCT series inverting buffer with 3-state outputs.

However, note the logic function differs: the CY74FCT240ATSOC is an inverting buffer, while the SN74ABT2245DW is a non-inverting transceiver with direction control. Pin compatibility should be verified against the respective datasheets."},{"question":"Is CY74FCT240ATSOC pin compatible with SN74FCT240?","answer":"The CY74FCT240ATSOC and the SN74FCT240 share the same logic function (dual 4-bit inverting buffer with 3-state outputs) and package footprint (20-SOIC wide). Pin compatibility is expected across the 74FCT240 variants, but always confirm with the specific datasheet for the SN74FCT240 version you are considering."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/CY74FCT240ATSOC","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/CY74FCT240ATSOC when reusing this data.
