LM2901XP from Jiangsu RUNIC Tech, 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 | OUTB | output | Open-drain output of channel B; outputs can be tied to other open-collector outputs for wired-AND. |
| 2 | OUTA | output | Open-drain output of channel A; outputs can be tied to other open-collector outputs for wired-AND. |
| 3 | V+ | power_in | Positive (highest) power supply; VS = (V+) - (V-) operates from 3.3 V to 32 V single-supply (absolute maximum 36 V). |
| 4 | -INA | input | Inverting input of channel A; input signals must stay within the common-mode range, which extends to ground and up to (V+) - 1.5 V at 25 °C (V+) - 2.0 V over -40 °C to +125 °C. |
| 5 | +INA | input | Noninverting input of channel A; input signals must stay within the common-mode range, which extends to ground and up to (V+) - 1.5 V at 25 °C (V+) - 2.0 V over -40 °C to +125 °C. |
| 6 | -INB | input | Inverting input of channel B; input signals must stay within the common-mode range, which extends to ground and up to (V+) - 1.5 V at 25 °C (V+) - 2.0 V over -40 °C to +125 °C. |
| 7 | +INB | input | Noninverting input of channel B; input signals must stay within the common-mode range, which extends to ground and up to (V+) - 1.5 V at 25 °C (V+) - 2.0 V over -40 °C to +125 °C. |
| 8 | -INC | input | Inverting input of channel C; input signals must stay within the common-mode range, which extends to ground and up to (V+) - 1.5 V at 25 °C (V+) - 2.0 V over -40 °C to +125 °C. |
| 9 | +INC | input | Noninverting input of channel C; input signals must stay within the common-mode range, which extends to ground and up to (V+) - 1.5 V at 25 °C (V+) - 2.0 V over -40 °C to +125 °C. |
| 10 | -IND | input | Inverting input of channel D; input signals must stay within the common-mode range, which extends to ground and up to (V+) - 1.5 V at 25 °C (V+) - 2.0 V over -40 °C to +125 °C. |
| 11 | +IND | input | Noninverting input of channel D; input signals must stay within the common-mode range, which extends to ground and up to (V+) - 1.5 V at 25 °C (V+) - 2.0 V over -40 °C to +125 °C. |
| 12 | V- | power_in | Negative (lowest) power supply; the supply is measured as (V+) - (V-), so this pin sets the lower rail for the 3.3 V to 32 V single-supply or ±1.65 V to ±16 V dual-supply ranges. |
| 13 | OUTD | output | Open-drain output of channel D; outputs can be tied to other open-collector outputs for wired-AND. |
| 14 | OUTC | output | Open-drain output of channel C; outputs can be tied to other open-collector outputs for wired-AND. |
