(1) These specifications are limited to −55°C≤TA≤+125°C, for the LM193/LM193A. With the LM293 all temperature specifications are limited to −25°C≤TA≤+85°C and the LM393 temperature specifications are limited to 0°C≤TA≤+70°C. The LM2903 is limited to −40°C≤TA≤+85°C.
(2) 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.
(3) 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+−1.5 V at 25°C, but either or both inputs can go to 36 V without damage, independent of the magnitude of V+.
(4) The response time specified is for a 100 mV input step with 5 mV overdrive. For larger overdrive signals 300 ns can be obtained, see LMx93 and LM193A Typical Characteristics .
(5) At output switch point, VO≃1.4V, RS= 0 Ω with V+ from 5V to 30V; and over the full input common-mode range (0V to V+−1.5V), at 25°C.
