MCP6561UT-E

MSKSEMI · Comparators · SOT-23-5

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.
