LM392DR from Texas Instruments, in a SOIC-8. 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 | OUTPUT A (Comparator) | output | Comparator A output is compatible with all types of logic systems, with low saturation voltage of 250 mV at 4 mA and direct interface to TTL or CMOS logic. |
| 2 | INVERTING INPUT A | input | Inverting input of comparator A; the input voltage must not go below -0.3 V and either input can go to 32 V without damage. |
| 3 | NONINVERTING INPUT A | input | Noninverting input of comparator A; the input voltage must not go below -0.3 V and the common-mode input range includes ground. |
| 4 | GND | power_in | Ground reference pin; the input common-mode range includes ground, allowing sensing at or near ground. |
| 5 | NONINVERTING INPUT B | input | Noninverting input of the operational amplifier B; the common-mode range is 0 V to V+ - 1.5 V and the input must not go below -0.3 V. |
| 6 | INVERTING INPUT B | input | Inverting input of the operational amplifier B; the common-mode range is 0 V to V+ - 1.5 V and the input must not go below -0.3 V. |
| 7 | OUTPUT B (Operational Amplifier) | output | Operational amplifier B output swings from 0 V to V+ - 1.5 V with a 2 kΩ load, and a short to ground is limited to approximately 40 mA. |
| 8 | V+ | power_in | Positive supply: 3 V to 32 V single supply, or ±1.5 V to ±16 V dual supply. |
