CC
This parameter is determined by device characterization but is not production tested.
ΔI
All currents are in milliamps and all frequencies are in megahertz.
For Max. or Min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device.
Typical values are at Vcc = 3.3V, +25°C ambient.
Per TTL driven input; all other inputs at Vcc or GND.
This parameter is not directly testable, but is derived for use in Total Power Supply Calculations.
Values for these conditions are examples of the Icc formula. These limits are guaranteed but not tested.
