PARAMETER
All voltages referenced to ground.
Active supply current combines the standby current with the output current. The output current is defined by
I = (C
This is the change observed in output frequency due to changes in temperature or voltage.
This parameter is guaranteed by design.
This indicates the time between power-up and the outputs becoming active.
