1. At output switch point, VO ≈ 1.4 V, RS = 0 Ω with Vcc from 5 V to 36 V, and over the full input common-mode range (0 V to

Vcc –1.5 V).

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.
