LM2903DTR from XBLW, 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 | Output of comparator 1 (open-collector type output, leakage specified up to 20 mA max rating, sink current typ 16 mA). |
| 2 | IN1- | input | Inverting input of comparator 1; input common-mode range -0.3 V to 36 V. |
| 3 | IN1+ | input | Noninverting input of comparator 1; input common-mode range -0.3 V to 36 V. |
| 4 | GND | power_in | Ground; negative supply for dual-supply operation. |
| 5 | IN2+ | input | Noninverting input of comparator 2; input common-mode range -0.3 V to 36 V. |
| 6 | IN2- | input | Inverting input of comparator 2; input common-mode range -0.3 V to 36 V. |
| 7 | OUT2 | output | Output of comparator 2 (open-collector type output, leakage specified up to 20 mA max rating, sink current typ 16 mA). |
| 8 | VCC | power_in | Positive power supply; single supply 2.0 V to 36 V, absolute maximum 36 V (±18 V dual). |
