(1)
All characteristics are measured under open-loop conditions, with zero common-mode input voltage, unless otherwise specified. MAX
VCC for testing purposes is 30 V.
(2)
Full range is
55°C to 125°C for LM139A.
(3)
All typical values are at TA = 25°C.
(4)
The input common mode voltage or either input signal voltage should not be allowed to go negative by more that 0.3 V. The upper end
of the common mode voltage range is V+ -1.5 V for TA = 25°C or V+ -2.0 V for TA = Full range, but either or both inputs can go to +30 V
dc without damage 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 V dc or 0.3 V dc below
the magnitude of the negative power supply, if used.
