MCP6561UT-E from MSKSEMI, 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 | +IN | input | Noninverting comparator input; the datasheet specifies a common-mode range that includes ground, from (V-) - 0.1 V up to 4.5 V at VS = 5 V. |
| 2 | V- | power_in | Negative (lowest) power supply pin; single-supply operation spans 2.1 V to 5.5 V from V+ to V-. |
| 3 | -IN | input | Inverting comparator input; it shares the same common-mode range limits as the noninverting input. |
| 4 | OUT | output | Open-drain comparator output that needs an external pull-up resistor to a logic supply; the datasheet lists a pull-up voltage range up to 5.6 V and sinking current up to 50 mA at VO ≤ 1.5 V (VS = 5 V). |
| 5 | V+ | power_in | Positive (highest) power supply pin; the absolute maximum supply voltage (V+) - (V-) is 7 V and the recommended range is 2.1 V to 5.5 V. |
