NOTES:
4. Minimum differential input voltage required to ensure a defined output state.
5. Input bias currents are essentially constant with differential input voltages up to
±
9V. With differential input voltages from
±
9V to
±
15V, bias cur-
rent on the more negative input can rise to approximately 500
μ
A. This will also cause higher supply currents.
6. V
CM
= 0V. Input sensitivity is the worst case minimum differential input voltage required to guarantee a given output logic state. This parameter
includes the effects of offset voltage and voltage gain.
7. For t
PD
(1); 100mV input step, -10mV overdrive. For t
PD
(0); -100mV input step, 10mV overdrive. Frequency
≈
100Hz; Duty Cycle
≈
50%; Invert-
ing input driven. See Figure 1 for Test Circuit. All unused inverting inputs tied to +5V.
8. For V
