Notes:

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

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

= Quiescent Current with CMOS input levels

∆I

CC

= Duty Cycle for TTL inputs HIGH

= Clock frequency for registered devices, otherwise zero

= Input signal frequency

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