MCP6541T-E 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 | Digital comparator output is CMOS/TTL-compatible push-pull and is capable of driving heavy DC or capacitive loads. |
| 2 | VSS | power_in | Negative power supply pin, typically connected to ground in single-supply operation; VDD must be 1.6V to 5.5V higher than VSS. |
| 3 | VIN+ | power_in | Non-inverting high-impedance CMOS comparator input with low bias current, operating rail-to-rail from VSS - 0.3V to VDD + 0.3V. |
| 4 | VIN- | power_in | Inverting high-impedance CMOS comparator input with low bias current. |
| 5 | VDD | power_in | Positive power supply pin, 1.6V to 5.5V above VSS, which needs a 0.01 µF to 0.1 µF bypass capacitor within 2 mm of the pin. |
