Product Overview
LM2903PWR is a dual open-collector comparator from Texas Instruments in TSSOP-8. The LM2903 family is widely used for threshold detection, window sensing, level conversion and oscillator functions where a simple comparator output can be pulled up to the required logic rail.
Its high supply-voltage capability makes it useful in industrial and automotive-adjacent control circuitry where 5 V-only comparators are not sufficient.

Open-Collector Output Considerations
The output requires an external pull-up resistor. That allows level shifting but means rise time depends on pull-up resistance and load capacitance; choose the resistor to balance speed and sink current.

For the same Texas Instruments LM2903 dual open-collector comparator in a wider SOIC footprint, compare LM2903DR (SOIC-8, D package) with this LM2903PWR (TSSOP-8, PW package). The comparator family is the same but the mechanical dimensions and PCB land patterns differ, so select the exact orderable package for the board rather than assuming a footprint swap.
