What the ratings mean for the BOM line
The SN74LV1T86DBVR: The 8 mA output drive at both high and low states is enough to fan out to a few CMOS inputs or drive a small LED indicator directly. Propagation delay is 7 ns at 5 V into a 30 pF load — fast enough for general-purpose logic up to a few tens of MHz, but not intended for high-speed memory interfaces. Industrial temperature range of -40°C to 125°C covers most factory-floor and outdoor equipment. The SOT-23-5 package is small enough for dense layouts but still hand-reworkable with a fine-tip iron and some patience — the pads are exposed and the part is small, so a hot-air station is cleaner than trying to drag-solder it.
Supply voltage flexibility and logic thresholds
The supply range from 1.6 V to 5.5 V means this gate works with 1.8 V, 2.5 V, 3.3 V, and 5 V logic families without needing a separate supply rail. The input low threshold is 0.58 V to 0.8 V, and the high threshold is 0.94 V to 2.1 V, so it correctly interprets signals from a 1.8 V microcontroller as well as a 5 V peripheral.
Sourcing and compliance
Texas Instruments lists this part as Active with ROHS3 compliance.
