LM211M

HGSEMI · Comparators · SOP-8

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.
