Parameters
For Max. or Min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device.
Typical values are at V
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 I
