MCP6541-I from Microchip Tech, in a SOIC-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 | NC | unconnected | No internal connection. |
| 2 | VIN- | power_in | Inverting input of the comparator, a high-impedance CMOS input with low bias current and rail-to-rail range of VSS - 0.3V to VDD + 0.3V. |
| 3 | VIN+ | power_in | Non-inverting input of the comparator, a high-impedance CMOS input with low bias current and rail-to-rail range of VSS - 0.3V to VDD + 0.3V. |
| 4 | VSS | power_in | Negative power supply, typically connected to ground in single-supply use; VDD is 1.6V to 5.5V higher than VSS. |
| 5 | NC | unconnected | No internal connection. |
| 6 | OUT | output | CMOS push-pull digital output, compatible with CMOS and TTL logic and capable of driving heavy DC or capacitive loads. |
| 7 | VDD | power_in | Positive power supply, 1.6V to 5.5V higher than VSS, with a local bypass capacitor of typically 0.01 µF to 0.1 µF within 2 mm of the pin. |
| 8 | NC | unconnected | No internal connection. |
