MCP6541RT-I from Microchip Tech, in a SOT-23-5. 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 | OUT | output | Push-pull CMOS/TTL-compatible digital output that is capable of driving heavy DC or capacitive loads. |
| 2 | VDD | power_in | Positive power supply, 1.6 V to 5.5 V higher than VSS, with a 0.01 µF to 0.1 µF local bypass capacitor recommended within 2 mm of the pin. |
| 3 | VIN+ | power_in | Non-inverting comparator input, a high-impedance CMOS input with low bias current, with a rail-to-rail input range of VSS - 0.3 V to VDD + 0.3 V. |
| 4 | VIN- | power_in | Inverting comparator input, a high-impedance CMOS input with low bias current, with a rail-to-rail input range of VSS - 0.3 V to VDD + 0.3 V. |
| 5 | VSS | power_in | Negative power supply pin, connected to ground in single-supply operation, with the other pins kept between VSS and VDD for normal operation. |
