LM2903AVQPWR from Texas Instruments, in a TSSOP-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 | output | Output of comparator 1, an open-drain NPN pull-down output that sinks current when IN- is above IN+ plus the offset voltage, so it needs an external pull-up. |
| 2 | 1IN- | input | Inverting input of comparator 1. |
| 3 | 1IN+ | input | Non-inverting input of comparator 1; for non-B-suffix devices the input common-mode range is 0 V to (V+) - 2.0 V. |
| 4 | GND | power_in | Ground reference pin for the device. |
| 5 | 2IN+ | input | Non-inverting input of comparator 2. |
| 6 | 2IN- | input | Inverting input of comparator 2. |
| 7 | 2OUT | output | Output of comparator 2, an open-drain NPN pull-down output that needs an external pull-up. |
| 8 | VCC | power_in | Positive supply pin; the recommended supply for V-suffix devices such as LM2903AV is 2 V to 32 V, with an absolute maximum of 36 V for non-B devices. |
