(1)
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.
(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+
−1.5V at 25°C, but either or both inputs can go to +30 VDC without damage (25V for LM3302),
independent of the magnitude of V+.
(4)
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.
