LM2903VQPWR 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 | tri_state | Output of comparator 1 with open-drain configuration that sinks up to 20mA when the inverting input (1IN-) exceeds the non-inverting input (1IN+). |
| 2 | 1IN− | input | Inverting input of comparator 1 accepting voltages from 0V to VCC-2V with maximum input bias current of 250nA. |
| 3 | 1IN+ | input | Non-inverting input of comparator 1 accepting voltages from 0V to VCC-2V with maximum input bias current of 250nA. |
| 4 | GND | power_in | Ground reference at 0V potential. |
| 5 | 2IN+ | input | Non-inverting input of comparator 2 accepting voltages from 0V to VCC-2V with maximum input bias current of 250nA. |
| 6 | 2IN- | input | Inverting input of comparator 2 accepting voltages from 0V to VCC-2V with maximum input bias current of 250nA. |
| 7 | 2OUT | tri_state | Output of comparator 2 with open-drain configuration that sinks up to 20mA when the inverting input (2IN-) exceeds the non-inverting input (2IN+). |
| 8 | VCC | power_in | Positive power supply for the device with operating voltage range from 2V to 32V and maximum total supply current of 2.5mA. |
