Notes:

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

∆I

= 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.
