The open-drain output lets you pull up to any voltage within the supply range, so a 5V comparator can drive a 3.3V MCU input directly. Maximum quiescent current is 2.5mA per device, which is modest for a dual comparator — not the lowest-power option for battery gear, but fine for line-powered industrial boards. Input offset voltage is 7mV max at 30V supply, and input bias current is 0.25µA max at 5V. For threshold detection in a 24V system (like an over-voltage latch), the 7mV offset translates to about 0.03% of the rail — negligible for most window comparators. The 0.25µA bias current means you can use high-value resistor dividers (100kΩ or more) without pulling the threshold off by more than a few millivolts. ## 8-TSSOP package and rework considerations Housed in an 8-TSSOP with 0.65mm pin pitch and 4.40mm body width. The package has no exposed pad, so thermal relief is through the leads only; keep the copper trace width at least 0.3mm per pin for adequate heat sinking in high-current output applications.","metaTitle":"Texas Instruments LM2903PWRG3 Dual Differential Comparator","metaDescription":"Texas Instruments LM2903PWRG3 dual differential comparator. 2V to 36V supply, open-drain/CMOS/TTL output, 8-TSSOP.
