Note 1: 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.
2: 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.
3: A duty cycle of no more than 60% (High time/Low time or Low time/High time) is recommended for external
clock inputs.
