The LM211 is identical to the LM111, except that its performance is specified over a −40°C to +85°C temperature range instead of −55°C to +125°C. The LM311 has a temperature range of 0°C to +70°C. The LM211Q has a temperature range of −40°C to +125°C. LMx11 consists of a PNP input stage to sense voltages near VCC–.

(4) The input common-mode voltage of either input signal voltage should not be allowed to go negative by more than 0.3 V (at 25°C). The upper end of the common-mode voltage range is V+ −1.5 V (at 25°C), but either or both inputs can go to 32 V without damage (26 V for LM2904), independent of the magnitude of V+.
