The 24 µs propagation delay is slow compared to high-speed comparators, but for low-frequency sensing — power-good flags, over-temperature trip points, window comparators — it is more than adequate and avoids the supply penalty of faster parts. Input offset voltage is specified at 6 mV max at 5 V, and CMRR/PSRR are 80 dB and 90 dB respectively — sufficient for rail-referenced thresholds but not precision null-detection.
A pin-compatible functional alternative is the TLV9032DDFR, which offers a faster 100 ns propagation delay and rail-to-rail input/output but draws higher quiescent current and is a dual-channel device in a different package. The LMC7215IM/NOPB remains the choice for single-channel, ultra-low-power threshold detection.
