Temperature range and industrial deployment
The 125°C ceiling is the junction temperature — derate the 8 mA output if ambient plus self-heating pushes toward that limit in a still-air enclosure.
Timing — 8.5 ns at 5V
Max propagation delay is 8.5 ns with a 5V supply driving 50 pF.
Quiescent draw and always-on circuits
Quiescent current maxes at 2 µA across the full voltage range. That makes this gate a candidate for battery-backed power-management logic or always-on supervisory circuits where every microamp counts.
