Dual differential comparator for industrial and automotive rails
Its output stage supports CMOS, MOS, open-drain, and TTL logic levels, so it can drive a microcontroller GPIO or a relay driver without extra translation.
Supply range and output flexibility
Rated supply from 2V to 36V means this comparator works on 3.3V, 5V, 12V, or 24V rails without a secondary regulator. 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.
