Note 1: Absolute Maximum Ratings are limits beyond which damage to the device may occur. Operating Ratings are conditions under which operation of the device

is derated to (-0.3V to 76V) at -40˚C.

Note 2: For detailed information on soldering the plastic TSSOP package, refer to the Packaging Databook available from National Semiconductor.

Note 3: Min and Max limits are 100% production tested at 25 ˚C. Limits over the operating temperature range are guaranteed through correlation using Statistical

Quality Control (SQC) methods. Limits are used to calculate National’s Average Outgoing Quality Level (AOQL).

Note 4: Device thermal limitations may limit usable range.

Note 5: Specification applies to the oscillator frequency. The operational frequency of the LM5071-50 devices is divided by two.
