(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 ensured specifications and test conditions, see the Electrical Characteristics
(2) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/Distributors for availability and
specifications.
(3) During rear auxiliary operation, the RTN pin can be approximately -0.4V with respect to VEE. This is caused by normal internal bias
currents, and will not harm the device. Application of external voltage or current must not cause the absolute maximum rating to be
exceeded.
(4) The human body model is a 100 pF capacitor discharged through a 1.5 kΩ resistor into each pin.
(5) For detailed information on soldering the plastic TSSOP package, refer to the Packaging Databook available from Texas Instruments.

(1) Minimum and Maximum limits are ensured through test, design, or statistical correlation using Statistical Quality Control (SQC) methods.
Typical values represent the most likely parametric norm at T
J
= 25°C, and are provided for reference purpose only. Limits are used to
calculate Texas Instruments' Average Outgoing Quality Level (AOQL).
