With a maximum quiescent current of 1µA, this part is aimed at battery-powered or always-on threshold sensing — think voltage monitors, window comparators, or wake-up circuits where every microamp counts. The 29µs propagation delay is not a speed demon; this is a low-power, low-speed comparator for DC or slow-changing signals, not for high-frequency switching or fast control loops. Typical applications include portable instrumentation, battery management, sensor threshold detection, and general-purpose level shifting where the open-drain output can be pulled up to a different voltage than the comparator's supply. ## Supply rails and the open-drain output — what to watch The supply range of 2V to 8V single (or ±1V to ±4V dual) is wide enough to cover common 3.3V and 5V rails. Yes, it works on a single 3.3V supply — that is squarely in the middle of the range. The open-drain output means the output pin sinks current to ground when active; the high level is set by the pull-up resistor voltage, which can be different from the comparator's VCC. This lets you interface a 5V-powered comparator to a 3.3V microcontroller input by pulling the output to 3.3V. The 6mV maximum input offset at 5V is adequate for most general-purpose threshold detection; if you need sub-millivolt precision, look at precision comparators with lower Vos. ## Package and rework — SOT-23-5 is a friendly footprint The LMC7225IM5 comes in a SC-74A / SOT-753 package, with the supplier device package listed as SOT-23-5. That is a standard 5-pin small-outline transistor package with 0.95 mm pitch. It reworks cleanly under hot air — low thermal mass, visible pin 1 mark (usually a dot or chamfer on the top), and no hidden pads. A fine-tip iron with a small hoof works too. No exposed pad to worry about, so no via-stitch or thermal pad requirement on the PCB. ## Lifecycle and sourcing posture This is a standard catalog part, available through independent distribution channels.","metaTitle":"LMC7225IM5 Comparator, General Purpose, Open Drain, SOT-23-5","metaDescription":"LMC7225IM5 general purpose comparator from Texas Instruments.

It is not a pin-compatible or direct functional replacement for the single-channel, open-drain LMC7225IM5.
