Output flexibility and input offset
The LM2903AVQPWR: The output stage supports CMOS, MOS, open-drain, or TTL logic families — the open-drain option lets multiple comparators share a pull-up for wired-OR configurations. Maximum input offset voltage is 2 mV at 5 V, and maximum input bias current is 0.25 µA at 5 V. These limits keep the threshold error small in precision sensing circuits like over-voltage detectors and zero-crossing triggers. Quiescent current maxes at 2.5 mA per device, and each output can sink or source 20 mA typical — enough to drive a logic input or a small LED indicator directly.
Store the reels dry — the MSL rating is not listed here, but the standard for TSSOP packages is typically MSL-1 or MSL-2; confirm with the reel label before opening the moisture barrier bag.
