5 µA quiescent — the battery-life spec that matters
In an always-on sensor node or a portable instrument, that 5 µA ceiling is what sets the standby budget — not the typical number. The push-pull output eliminates the pull-up resistor current that an open-drain comparator would burn.
4 mV hysteresis — no external feedback needed
Internal 4 mV hysteresis cleans up the switching threshold on a noisy signal without adding two external resistors. For a thermistor threshold detector or a zero-crossing circuit on a 3.3 V rail, that saves two components and a board inspection step. The 8 µs typical propagation delay is fast enough for 100 kHz-level switching but not for high-speed PWM loop control.
That covers outdoor telecom cabinets, factory-floor sensor interfaces, and automotive cabin or engine-bay environments. The 100 dB CMRR and 80 dB PSRR keep the threshold stable when the supply rail sags or the common-mode voltage drifts with temperature.
SOT-23-8 — two comparators in a small footprint
Two general-purpose comparators in an 8-pin SOT-23 package. The surface-mount SOT-23-8 is a standard footprint for automated assembly and rework.
