8. At the output switch point, V

(0 Vdc to V
CC
1.5 Vdc).
9. The bias current flows out of the inputs due to the PNP input stage. This current is virtually constant, independent of the output state.
10.The response time specified is for a 100 mV input step with 5.0 mV overdrive. For larger signals, 300 ns is typical.
