Note 2 For operation at elevated temperatures devices in the N package must be derated based on a thermal resistance of 86 C W junction to ambient Devices
in the M package must be derated at 125 C W junction to ambient
Note 3 Tested limits are guaranteed and 100% tested in production
Note 4 Design limits are guaranteed (but not 100% production tested) over the indicated temperature and supply voltage range These limits are not used to
calculate outgoing quality level
Note 5 Absolute maximum ratings indicate limits beyond which damage to the device may occur DC and AC electrical specifications do not apply when operating
the device beyond its rated operating conditions
Note 6 Pins 1 4 7 8 11 and 14 are grounded Pin 2
Note 7 The value of a C
capacitor can vary with frequency Careful selection of this capacitor must be made for high frequency operation Polystyrene was used in
t
this test NPO ceramic or polypropylene can also be used
Note 8 OSC amplitude is measured open circuit Available current is limited to 1 mA so care must be exercised to limit capacitive loading of fast pulses
