Product Overview
The LM2903AVQDRQ1 is TI’s active automotive-qualified SOIC-8 tape-and-reel orderable for the LM2903-Q1 dual comparator family. Its two open-collector comparator outputs support threshold detection, level monitoring and wired-logic functions across a wide supply range.
Open-collector outputs require external pull-up resistors. That architecture allows the logic-high voltage to be selected independently within the output limits.

Design Considerations
Each output requires a pull-up resistor sized for sink current and rise time. A high pull-up value reduces current but slows edges with capacitive loads.
Keep inputs inside the specified common-mode range even when absolute-maximum ratings are not exceeded.
