LP2901IDRQ1 from Texas Instruments, in a SOIC-14. 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 1OUT output Comparator 1 open-collector output that sinks 30 mA at VO = 2 V and can be pulled up to any supply within the permitted range.
2 2OUT output Comparator 2 open-collector output that sinks 30 mA at VO = 2 V and can be pulled up to any supply within the permitted range.
3 VCC power_in Positive supply input rated 3 V to 30 V recommended (36 V absolute maximum), reverse-voltage protected, and normally bypassed with a capacitor.
4 2IN− input Comparator 2 inverting input with a common-mode range of 0 to VCC − 1.5 V at 25°C, which should be grounded if the comparator is unused.
5 2IN+ input Comparator 2 non-inverting input with a common-mode range of 0 to VCC − 1.5 V at 25°C, which should be grounded if the comparator is unused.
6 1IN− input Comparator 1 inverting input with a common-mode range of 0 to VCC − 1.5 V at 25°C, which should be grounded if the comparator is unused.
7 1IN+ input Comparator 1 non-inverting input with a common-mode range of 0 to VCC − 1.5 V at 25°C, which should be grounded if the comparator is unused.
8 3IN− input Comparator 3 inverting input with a common-mode range of 0 to VCC − 1.5 V at 25°C, which should be grounded if the comparator is unused.
9 3IN+ input Comparator 3 non-inverting input with a common-mode range of 0 to VCC − 1.5 V at 25°C, which should be grounded if the comparator is unused.
10 4IN− input Comparator 4 inverting input with a common-mode range of 0 to VCC − 1.5 V at 25°C, which should be grounded if the comparator is unused.
11 4IN+ input Comparator 4 non-inverting input with a common-mode range of 0 to VCC − 1.5 V at 25°C, which should be grounded if the comparator is unused.
12 GND power_in Ground reference for the device, and the input voltage must not go below −0.3 V relative to it.
13 4OUT output Comparator 4 open-collector output that sinks 30 mA at VO = 2 V and can be pulled up to any supply within the permitted range.
14 3OUT output Comparator 3 open-collector output that sinks 30 mA at VO = 2 V and can be pulled up to any supply within the permitted range.
