It accepts a supply range of 2V to 6V, making it usable in both 3.3V and 5V logic domains. The -40°C to 125°C operating temperature range suits industrial environments such as motor drives, factory automation, and outdoor telecom equipment where temperature swings are routine. Each of the two 4-bit elements provides inverting drive with 7.8 mA source and sink capability, enough to drive standard HC inputs or short PCB traces. The 3-state outputs let multiple buffers share a common bus line without contention — a typical use case in address/data bus isolation or memory-mapped I/O expansion. ## Supply range and temperature — what they mean for the BOM The 2V to 6V supply range covers both 3.3V and 5V logic domains. At 5V the HC family's noise margins are generous; at 3.3V the output drive (7.8 mA) stays within the same rating. ## Lifecycle and sourcing reality The 74HC240PW,118 carries an Active product status with ROHS3 compliance. There is no last-time-buy notice or obsolescence risk on this line — Nexperia continues to manufacture the 74HC series in volume. For BOM freeze or production replenishment, this part is a safe selection.","metaTitle":"74HC240PW,118 Buffer/Line Driver, 3-State, 20-TSSOP, 2V–6V","metaDescription":"74HC240PW,118 octal inverting buffer/line driver with 3-state outputs. 2V–6V supply, -40°C to 125°C, 20-TSSOP.

The logic function, supply range, and temperature grade are identical. The PW variant is suited for modern SMT assembly; the N variant is for through-hole boards or prototyping."},{"question":"What is the function of 74HC240PW?","answer":"It is an octal inverting buffer/line driver with 3-state outputs. It drives bus lines or isolates logic signals, and the 3-state feature allows multiple outputs to share a common bus without contention."},{"question":"Can 74HC240PW be used as a replacement for 74HC240?","answer":"Yes, the 74HC240PW is the surface-mount variant of the 74HC240 logic function. The electrical specifications — supply range, drive current, temperature grade — are the same. The only difference is the package: 20-TSSOP vs. the original DIP or SOIC options."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/nxp/74HC240PW118","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/nxp/74HC240PW118 when reusing this data.
