Product Overview
LM2901DR2G is onsemi’s quad general-purpose comparator in SOIC-14 tape-and-reel packaging. Four independent comparator channels share the supply and provide open-collector outputs, allowing pull-up voltage selection and wired logic functions.
The device supports a broad 3 V to 36 V supply range, making it suitable for monitoring and threshold functions in mixed-voltage control systems.

Comparator Integration Considerations
Because the outputs are open collector, each used channel needs an appropriate pull-up. Input signals near the upper supply rail should also be checked against the comparator’s common-mode limits rather than assuming rail-to-rail input operation.
