(1) Absolute Maximum Ratings indicate limits beyond which damage to the component may occur. Operating Ratings are conditions under
which operation of the device is specified. Operating Ratings do not imply specified performance limits. For specified performance limits
and associated test conditions, see the Electrical Characteristics tables.
(2) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/ Distributors for availability and
specifications.
(3) Min and Max limits are production tested at 25°C. Limits over the operating temperature range are specified through correlation using
Statistical Quality Control (SQC) methods.
(4) The human body model is a 100 pF capacitor discharged through a 1.5 kΩ resistor into each pin.

ELECTRICAL CHARACTERISTICS
Specifications in standard typeface are for T_J = 25°C, and those in boldface type apply over the full operating junction
temperature range.⁽¹⁾. Typical values represent the most likely parametric norm at T_J = 25°C, and are provided for reference
purposes only. Unless otherwise stated the following conditions apply: V_D=V_A=5V.
