Output drive is symmetrical at 7.8mA sink and source, which is typical for HC logic but worth noting if you are fanning out to multiple CMOS inputs — budget the DC fan-out against the load, not just the AC drive. No last-time-buy window to manage, no forced redesign cycle. For a long-life automotive program, that is the difference between a one-time fit and a multi-year supply commitment. ## Package and footprint — 20-SOIC wide-body Supplied in a 20-SOIC wide-body (7.50 mm body width) package, surface-mount. The wide-body SOIC gives better thermal dissipation than the narrow version and is easier to inspect and rework. No exposed pad — standard SOIC land pattern applies.","metaTitle":"74HC540D-Q100118 Automotive AEC-Q100 Inverting Buffer, 2V-6V","metaDescription":"74HC540D-Q100118 AEC-Q100 qualified inverting buffer with 3-state outputs. 2V to 6V supply, -40°C to 125°C, 20-SOIC.

The Q100 suffix is the AEC-Q100 qualified variant — same footprint, same function, but the standard grade lacks the extended temperature range and automotive qualification. For a direct automotive-grade substitute, stick with the Q100 variant."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/nxp/74HC540D-Q100118","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/nxp/74HC540D-Q100118 when reusing this data.
