(1) These specifications are limited to −55°C ≤TA≤125°C, for the LM139/LM139A. 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= 0 Ωwith V+from 5 VDC 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 VDC 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 0.3 V. 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) The response time specified is a 100-mV input step with 5-mV overdrive. For larger overdrive signals 300 ns can be obtained, see
typical performance characteristics section.
(6) 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).
