MCP6542T-I from Microchip Tech, in a MSOP-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 | OUTA | output | Comparator A push-pull digital output, CMOS/TTL-compatible and capable of driving heavy DC or capacitive loads. |
| 2 | VINA- | input | Comparator A inverting input, a high-impedance CMOS input with low bias currents. |
| 3 | VINA+ | input | Comparator A non-inverting input, a high-impedance CMOS input with low bias currents. |
| 4 | VSS | power_in | Negative power supply pin, lower in voltage than VDD and connected to ground in single-supply operation. |
| 5 | VINB+ | input | Comparator B non-inverting input, a high-impedance CMOS input with low bias currents. |
| 6 | VINB- | input | Comparator B inverting input, a high-impedance CMOS input with low bias currents. |
| 7 | OUTB | output | Comparator B push-pull digital output, CMOS/TTL-compatible and capable of driving heavy DC or capacitive loads. |
| 8 | VDD | power_in | Positive power supply pin rated 1.6V to 5.5V, needing a local bypass capacitor of typically 0.01 µF to 0.1 µF within 2 mm. |
