Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

Note 2: Guaranteed by design.
Note 3: Under these conditions: a) no spurious oscillations shall be observed at collector greater than -60dBc; b) no parametric
degradation is observable when mismatch is removed; and c) no current draw in excess of the package dissipation
capability is observed.
