MCP6541RT-I

Microchip Tech · Comparators · SOT-23-5

MCP6541RT-I 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 Push-pull CMOS/TTL-compatible digital output that is capable of driving heavy DC or capacitive loads.
2 VDD power_in Positive power supply, 1.6 V to 5.5 V higher than VSS, with a 0.01 µF to 0.1 µF local bypass capacitor recommended within 2 mm of the pin.
3 VIN+ power_in Non-inverting comparator input, a high-impedance CMOS input with low bias current, with a rail-to-rail input range of VSS - 0.3 V to VDD + 0.3 V.
4 VIN- power_in Inverting comparator input, a high-impedance CMOS input with low bias current, with a rail-to-rail input range of VSS - 0.3 V to VDD + 0.3 V.
5 VSS power_in Negative power supply pin, connected to ground in single-supply operation, with the other pins kept between VSS and VDD for normal operation.
