Electrical Characteristics
JA
Specifications in standard type face are for T
perature range. Unless otherwise specified: V
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 intended to be functional. For guaranteed specifications and test conditions, see the Electrical Characteristics.
Note 2: For detailed information on soldering plastic TSSOP and LLP 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 LM5070-50 devices is divided by two.
