Electrical Characteristics
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: The maximum allowable power dissipation is a function of the maximum junction temperature, T
the ambient temperature, T
Where the value of θ
device will go into thermal shutdown.
Note 3: The human body model is a 100pF capacitor discharged through a 1.5kΩ resistor into each pin. The machine model is a 200pF capacitor discharged directly
into each pin. The machine model ESD rating for pin 5 and pin 6 is 150V.
Note 4: Limits are 100% production tested at 25˚C. Limits over the operating temperature range are guaranteed through correlation using Statistical Quality Control
(SQC) methods. The limits are used to calculate National’s Average Outgoing Quality Level (AOQL).
Note 5: Typical numbers represent the most likely parametric norm for 25˚C operation.
