The 2.5 mA maximum quiescent current across all four channels keeps the thermal budget low even at the 125°C end of the temperature range. ## Open-collector outputs and 20 mA sink capability Each of the four comparators drives an open-collector output rated for 20 mA typical sink current. The output type — CMOS, MOS, open-collector, or TTL-compatible — lets the designer pull up to any voltage within the supply range, making the part suitable for level-shifting between logic families or driving a relay coil through an external pull-up resistor. The 0.25 µA maximum input bias current at 5 V preserves accuracy in high-impedance sensor circuits. ## Package and footprint — 14-SOIC","metaTitle":"LM2901QDRQ1 Quad Differential Comparator, AEC-Q100, 14-SOIC","metaDescription":"Texas Instruments LM2901QDRQ1 quad differential comparator.
