Automotive-grade inverting buffer for harsh environments
The Nexperia 74HC540N-Q100112 is an automotive-qualified (AEC-Q100) single-element 8-bit inverting buffer with 3-state outputs, housed in a 20-DIP through-hole package.
What the AEC-Q100 qualification means for your BOM
The -Q100 suffix on this part signals full AEC-Q100 stress qualification — the same 74HC540 logic function, but tested to automotive-grade reliability standards including extended temperature cycling, ESD tolerance, and parametric drift limits. The output drive is rated 7.8mA for both high and low states, consistent with the 74HC family's balanced drive.
Through-hole 20-DIP — board-level fit
No MSL concern — through-hole DIPs are moisture-insensitive. The single-element, 8-bit architecture means one package handles an entire 8-bit bus, simplifying layout for address or data line buffering.
