LM211M from HGSEMI, in a SOP-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 | GND | power_in | Ground pin; the output can be referenced to ground, and the datasheet notes input polarity reverses when GND is used as the output reference. |
| 2 | IN+ | input | Non-inverting comparator input; differential input voltage up to 30 Vdc and input voltage up to 15 Vdc (with ±15V supplies). |
| 3 | IN- | input | Inverting comparator input; differential input voltage up to 30 Vdc and input voltage up to 15 Vdc (with ±15V supplies). |
| 4 | VEE | power_in | Negative supply; VEE to ground is limited to 30 Vdc and total supply VCC+VEE to 36 Vdc. |
| 5 | BALANCE | passive | Offset balance pin used for input offset voltage trimming. |
| 6 | BALANCE/STROBE | input | Shared balance and strobe pin; strobe voltage range is VCC to VCC-5 V and it must not be tied directly to ground but driven with 3 mA to 5 mA. |
| 7 | OUTPUT | output | Open-collector/emitter output that can switch up to 50 V (LM211) at 50 mA, with VO-VEE rated 50 Vdc for LM211 and 40 Vdc for LM311. |
| 8 | VCC | power_in | Positive supply; operates from a single 5V to 30V supply or dual ±15V supplies, with total VCC+VEE up to 36 Vdc. |
