Notes:

14. For conditions shown as Max. or Min., use appropriate value speciﬁed under Electrical Characteristics for the applicable device type.

15. This parameter is not directly testable, but is derived for use in Total Power Supply Current.

16. I_C= I_QUIESCENT+ I_INPUTS+ I_DYNAMIC

f₀

Quiescent Current with CMOS input levels

Power Supply Current for a TTL HIGH input (V_IN=3.4V)

Duty Cycle for TTL inputs HIGH

Number of TTL inputs at D_H

Dynamic Current caused by an input transition pair (HLH or LHL)

Clock frequency for registered devices, otherwise zero

Input signal frequency

f₁

N₁

Number of inputs changing at f₁

All currents are in milliamps and all frequencies are in megahertz.

17. Values for these conditions are examples of the I_CCformula. These limits are speciﬁed but not tested.
