Product details

Dual differential comparator with wide supply and temperature range

The LM2903DGKRG4: Its open-drain output stage allows wired-OR configurations and level translation to higher-voltage logic families.

This part carries a Last Buy product status. That means TI has scheduled end-of-life and the final purchasing window is open. Any BOM using the LM2903DGKRG4 needs a replacement plan before the Last Buy deadline passes and the part becomes unavailable through authorized channels.

The 2V to 36V single-supply range covers common logic and battery rails. Maximum quiescent current is 2.5mA.

The 8-VSSOP (MSOP-8) body is 3.00 mm wide.
