LM2903BRQDGKRQ1

Texas Instruments · Comparators · VSSOP-8

LM2903BRQDGKRQ1 from Texas Instruments, in a VSSOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 1OUT tri_state Comparator 1 output; open-drain configuration with 25 mA maximum sink current, voltage rating −0.3 to 38 V.
2 1IN- input Comparator 1 negative input; voltage rating −0.3 to 38 V, common-mode range (V−) to (V+)−1.5 V.
3 1IN+ input Comparator 1 positive input; voltage rating −0.3 to 38 V, common-mode range (V−) to (V+)−1.5 V.
4 GND power_in Ground reference; thermal die pad must be connected directly to ground.
5 2IN+ input Comparator 2 positive input; voltage rating −0.3 to 38 V, common-mode range (V−) to (V+)−1.5 V.
6 2IN- input Comparator 2 negative input; voltage rating −0.3 to 38 V, common-mode range (V−) to (V+)−1.5 V.
7 2OUT tri_state Comparator 2 output; open-drain configuration with 25 mA maximum sink current, voltage rating −0.3 to 38 V.
8 VCC power_in Positive power supply voltage; supply range 2 to 36 V for LM2903B-Q1.
