LM2903NS08ARBE

GR · Comparators · SOP-8

LM2903NS08ARBE from GR, in a SOP-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 OUT1 output Open-drain output of comparator 1, which can be wired-AND with other open-collector outputs.
2 IN1- input Negative (inverting) input of comparator 1; the voltage at this input should not go negative by more than 0.3 V, or the output may be incorrect and excessive input current can flow.
3 IN1+ input Positive (non-inverting) input of comparator 1; the voltage at this input should not go negative by more than 0.3 V, or the output may be incorrect and excessive input current can flow.
4 GND power_in Ground pin; all voltage values except differential voltages are referenced to network ground.
5 IN2+ input Positive (non-inverting) input of comparator 2; the voltage at this input should not go negative by more than 0.3 V, or the output may be incorrect and excessive input current can flow.
6 IN2- input Negative (inverting) input of comparator 2; the voltage at this input should not go negative by more than 0.3 V, or the output may be incorrect and excessive input current can flow.
7 OUT2 output Open-drain output of comparator 2, which can be wired-AND with other open-collector outputs.
8 VCC power_in Single supply pin; the datasheet specifies a single supply voltage of 2 V to 32 V (dual supply ±16 V also possible).
