(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 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 1.5k

Ω resistor into each pin.

(4)

The maximum allowable power dissipation is a function of the maximum allowed junction temperature (TJ(max)), the ambient temperature

(TA), and the junction-to-ambient thermal resistance (θJA). The maximum allowable power dissipation can be calculated from PD =

(TJ(max) - TA) / θJA. Excessive power dissipation will cause the thermal shutdown to activate.

(5)

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 specifications and test conditions, see the Electrical Characteristics.

Electrical Characteristics

Specifications with standard typeface are for TJ = 25°C, and those with boldface type apply over full Operating Junction

Temperature range. VIN = 48V, VCC = 10V applied externally, RT = 26.7kΩ, unless otherwise stated. See

(1) and (2).

(1)

Min and Max limits are 100% production tested at 25°C. Limits over the operating temperature range are specified through correlation

using Statistical Quality Control (SQC) methods. Limits are used to calculate TI’s Average Outgoing Quality Level (AOQL).

(2)

Typical specifications represent the most likely parametric norm at 25°C operation.
