Note 1:
‘‘Absolute Maximum Ratings’’ are those values beyond which the safety of the device cannot be guaranteed. Except for ‘‘Operating Temperature Range’’
they are not meant to imply that the devices should be operated at these limits. The table of ‘‘Electrical Characteristics’’ provides conditions for actual device
operation.
Note 2:
Unless otherwise specified min/max limits apply across the

Note 3:
All currents into device pins are shown as positive, out of device pins as negative, all voltages referenced to ground unless otherwise noted. All values
shown as max or min on absolute value basis.
Note 4:

e
the period of time the modulus control level must be defined prior to the positive transition of the prescaler output to ensure proper modulus
selection.
Note 5:
See Timing Diagrams.
Timing Diagram
TL/F/5240–3
The logical state of the modulus control input just prior to the output’s rising edge will determine the modulus ratio of the device
immediately following that rising edge. The pulse width difference of N and N
a
1 operation occurs during the output
