LM211MM from HGSEMI, in a MSOP-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 with GND used as the output reference the input polarity is reversed. |
| 2 | IN+ | input | Non-inverting (+) comparator input, isolated from system ground; input voltage rated 15 V with ±15 V supplies and differential voltage up to 30 V. |
| 3 | IN- | input | Inverting (-) comparator input, isolated from system ground; input voltage rated 15 V with ±15 V supplies and differential voltage up to 30 V. |
| 4 | VEE | power_in | Negative supply; total VCC+VEE is limited to 36 V and ground to VEE to 30 V. |
| 5 | BALANCE | passive | Balance pin for input offset voltage adjustment. |
| 6 | BALANCE/STROBE | input | Shared balance and strobe pin; must not be tied directly to ground and needs to be driven with 3 mA to 5 mA, with strobe voltage limited to VCC to VCC-5 V. |
| 7 | OUTPUT | output | Comparator output that can be referenced to ground, VCC or VEE to drive DTL, RTL, TTL or MOS logic, and can switch up to 50 V at 50 mA (VO-VEE max 50 V for LM211, 40 V for LM311). |
| 8 | VCC | power_in | Positive supply; operates from a single 5 V to 30 V supply or ±15 V dual supply, with VCC+VEE max 36 V. |
