4.At the output switch point, VO
(0 Vdc to VCC –1.5 Vdc).
5.The bias current flows out of the inputs due to the PNP input stage. This current is virtually constant, independent of the output state.
6.The response time specified is for a 100 mV input step with 5.0 mV overdrive. For larger signals, 300 ns is typical.
