Microchip Tech · Comparators · SOIC-8
MCP6542-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 | OUTA | output | Comparator A digital output is CMOS/TTL-compatible push-pull and is capable of driving heavy DC or capacitive loads. |
| 2 | VINA- | input | Comparator A inverting input is a high-impedance CMOS input with low bias current and rail-to-rail operation from VSS - 0.3V to VDD + 0.3V. |
| 3 | VINA+ | input | Comparator A non-inverting input is a high-impedance CMOS input with low bias current and rail-to-rail operation from VSS - 0.3V to VDD + 0.3V. |
| 4 | VSS | power_in | Negative power supply pin, connected to ground in single-supply operation, with VDD rated 1.6V to 5.5V above it. |
| 5 | VINB+ | input | Comparator B non-inverting input is a high-impedance CMOS input with low bias current and rail-to-rail operation from VSS - 0.3V to VDD + 0.3V. |
| 6 | VINB- | input | Comparator B inverting input is a high-impedance CMOS input with low bias current and rail-to-rail operation from VSS - 0.3V to VDD + 0.3V. |
| 7 | OUTB | output | Comparator B digital output is CMOS/TTL-compatible push-pull and is capable of driving heavy DC or capacitive loads. |
| 8 | VDD | power_in | Positive power supply pin rated 1.6V to 5.5V, requiring a local bypass capacitor of 0.01 µF to 0.1 µF within 2 mm of the pin. |
