With the LM239/LM239A, all temperature specifications are limited to −25°C ≤ TA ≤ +85°C, the LM339/LM339A temperature specifications are limited to 0°C ≤ TA ≤ +70°C, and the LM2901, LM3302 temperature range is −40°C ≤ TA ≤ +85°C. (2) At output switch point, VO≃1.4 VDC, RS = 0Ω with V + from 5 V DC to 30 VDC; and over the full input common-mode range (0 VDC to V + −1.5 VDC), at 25°C. For LM3302, V + from 5 V DC to 28 VDC. (3) The direction of the input current is out of the IC due to the PNP input stage. This current is essentially constant, independent of the state of the output so no loading change exists on the reference or input lines. (4) The input common-mode voltage or either input signal voltage should not be allowed to go negative by more than 0.3V. The upper end of the common-mode voltage range is V+ −1.5V at 25°C, but either or both inputs can go to +30 VDC without damage (25V for LM3302), independent of the magnitude of V+. (5) Positive excursions of input voltage may exceed the power supply level. As long as the other voltage remains within the common-mode range, the comparator will provide a proper output state. The low input voltage state must not be less than −0.3 VDC (or 0.3 VDCbelow the magnitude of the negative power supply, if used) (at 25°C).
