(1)
Absolute Maximum Ratings indicate limits beyond witch damage to the device may occur. Operating Ratings indicate conditions for
which the device is intended to be functional, but do not ensure specific performance limits. 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)
The human body model is a 100 pF capacitor discharged through a 1.5 k
Ω resistor to each pin.
Operating Ratings
VIN to GND
+4.5V to +36V
Junction Temperature
−40°C to + 125°C
Electrical Characteristics
Unless otherwise stated, the following conditions apply: VVIN = 12V. Limits in standard type are for TJ = 25°C only, limits in
bold face type apply over the junction temperature (TJ) range of -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
TJ = 25°C, and are provided for reference purposes only.
