POWER SUPPLY CHARACTERISTICS
NOTES:
1. For conditions shown as Max. or Min., use appropriate value specified under Electrical Characteristics for the applicable device type.
2. Typical values are at V
3. Per TTL driven input. All other inputs at V
4. This parameter is not directly testable, but is derived for use in Total Power Supply Calculations. It is derived with Q frequency as the reference.
5. Values for these conditions are examples of the I
6. I
SYNCH INPUT TIMING REQUIRMENTS
NOTES:
1. Note 7 in "General AC Specification Notes" and Figure 3 describes this specification and its actual limits depending on the feedback connection.
2. Maximum operating frequency is guaranteed with the part in a phase locked condition and all outputs loaded.
3. At this frequency, 2Q cannot be used as feedback.
