NOTES
1
Temperature Ranges are as follows: B Version, 40°C to +85°C; Y Version, 40°C to +105°C.
2
See Terminology.
3
Guaranteed by design and characterization, not production tested.
4
The absolute input voltage on the different input pins must not go more positive than Vdd - 2V or more negative than GND - 400mV. The common-mode voltage
applies to those inputs which form differential pairs.
Span = Max output frequency - Min output frequency
