1.
At output switch point, Vo ≈ 1.4V, Rs = 0 with VCC
+ from 5V to 30V, and over the full common-mode range (0V to V
CC
+ -1.5V).

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 charge exists on the reference of input lines.
