Note 2: At output switch point, VO=1.4V, RS=0 with VCC from 5V to 15V, and over the full common-mode range
(0V to VCC - 1.5V), at 25oC.
Note 3: The direction of the input current is out of the PNP input stage. This current is essentially constant, indepen-
dent of the state of the output, so no loading charge exists on the reference of input lines.
Note 4: The input common-mode voltage of 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 VCC - 1.5V, but either or both inputs can go to
+18V without damage, independent of the magnitude of VCC.
Note 5: The response time specified is a 100mV input step with 5mV overdrive. For large overdrive signals 300ns
can be obtained.
