Data in the Typical (“Typ”) column is at 5V, 25°C unless otherwise stated. These parameters are for design
guidance only and are not tested.
These parameters are for design guidance only and are not tested.
All specified values are based on oscillator characterization data under standard operating conditions.
Exceeding these specified limits may result in unstable oscillator operation and/or higher than expected
current consumption. When an external clock input is used, the “max” cycle time limit is “DC” (no clock) for
all devices.
A duty cycle of no more than 60% (High time/Low time or Low time/High time) is recommended for external
clock inputs.
