Automotive-grade dual buffer for mixed-voltage busses
It operates across a wide supply range of 1.65V to 5.5V, covering 1.8V, 2.5V, 3.3V, and 5V logic rails without needing a separate level translator. Each of the two channels can source or sink 32mA, enough to drive multiple loads or long PCB traces in a noisy automotive environment. The part comes in the compact SM8 package (8-LSSOP or 8-MSOP), a standard footprint for space-constrained ECU and sensor modules.
Supply voltage range — one part for 1.8V to 5V rails
In a mixed-voltage design — say a 3.3V MCU talking to a 5V sensor — the 74LVC family's 5V-tolerant inputs let you avoid external level shifters.
If your application requires operation above 85°C — for example, direct engine-bay mounting — check the thermal profile; the 125°C-rated sibling SN74LVC2G17QDCKRQ1 might be needed.
For automotive programs that run five to ten years, that means the BOM line is stable — no forced redesign from obsolescence.
