The open-collector output stage sinks up to 16 mA at 5V and interfaces directly with CMOS, TTL, DTL, ECL, or MOS logic — no level shifter needed between the comparator and the digital input. Maximum input offset voltage is 7 mV at 30V supply. For a 5V threshold with a 100 mV hysteresis band, that 7 mV offset contributes about 7% uncertainty — acceptable for overvoltage/undervoltage detection but worth derating if you are sensing a 50 mV current-shunt drop. Maximum input bias current is 0.25 µA at 5V. In a high-impedance divider (say 1 MΩ total), that bias drops 0.25 V across the resistor — enough to shift the trip point. Keep the divider impedance below 100 kΩ to keep the bias error under 25 mV. ## Quiescent draw and production status Maximum quiescent current for both comparators is 1 mA. In a 24 V always-on industrial sensor, that is 24 mW — negligible for a bulk supply but a line item in a loop-powered 4-20 mA transmitter where the total budget is 3.5 mA.","metaTitle":"LM2903MX-TI Dual Comparator, 2V-36V Supply","metaDescription":"Texas Instruments LM2903MX-TI dual general-purpose comparator. 2V to 36V supply range, open-collector output drives CMOS/TTL.
