MCP6541T-I from Microchip, in a SC-70-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	NC	unconnected	No internal connection. Leave floating or tie to a convenient net; no electrical function inside the package.
2	VIN-	input	Inverting analog input of the comparator (rail-to-rail). Common-mode input range VSS-0.3 V to VDD+0.3 V. High-impedance CMOS input with sub-pA typical input bias current (IB ~1 pA typical).
3	VIN+	input	Non-inverting analog input of the comparator (rail-to-rail). Common-mode input range VSS-0.3 V to VDD+0.3 V. High-impedance CMOS input with sub-pA typical input bias current.
4	VSS	power_in	Negative supply / ground reference. Typically connected to system GND in a single-supply configuration.
5	NC	unconnected	No internal connection. Leave floating or tie to a convenient net; no electrical function inside the package.
6	OUT	output	Push-pull CMOS/TTL-compatible digital output. Rail-to-rail: VOH ≥ VDD-0.2 V at IOUT=-2 mA, VOL ≤ VSS+0.2 V at IOUT=2 mA (VDD=5 V). Short-circuit current limited (typ ±30 mA at VDD=5.5 V); absolute max continuous output current is ±30 mA.
7	VDD	power_in	Positive supply, 1.6 V to 5.5 V. Bypass with 0.01 μF to 0.1 μF within 2 mm of the pin. Quiescent current IQ = 0.6 μA typical (1.0 μA max) per comparator.
8	NC	unconnected	No internal connection. Leave floating or tie to a convenient net; no electrical function inside the package.
