Electrical Characteristics
apply over the full Operating Temperature Range (T
J
= -40°C to +125°C). Minimum and Maximum limits are guaranteed through
test, design or statistical correlation. Typical values represent the most likely parametric norm at T
J
= 25°C and are provided for
reference purposes only. V
CC
= 3.3V, unless otherwise specified.

Note 1:
Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
intended to be functional, but does not guarantee specific performance limits. For guaranteed specifications and conditions, see the Electrical Characteristics.
Note 2:
The human body model is a 100 pF capacitor discharged through a 1.5 k
resistor into each pin.
Note 3:
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 4:
Typical numbers are at 25°C and represent the most likely parametric norm.
