6.3 Electrical Characteristics

Unless otherwise specified under the Conditions column, V_IN = 5 V. Limits in standard type are for T_J = 25°C only; limits in boldface type apply over the junction temperature (T_J) range of –40°C to +125°C. Minimum and Maximum limits are ensured through test, design, or statistical correlation. Typical values represent the most likely parametric norm, and are provided for reference purposes only.

(1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur, including inoperability and degradation of device reliability and/or performance. Functional operation of the device and/or non-degradation at the Absolute Maximum Ratings or other conditions beyond those indicated in the recommended Operating Ratings is not implied. The recommended Operating Ratings indicate conditions at which the device is functional and should not be operated beyond such conditions.

(2) Thermal shutdown occurs if the junction temperature exceeds the maximum junction temperature of the device.

(3) Applies for packages soldered directly onto a 4” × 3” 4-layer standard JEDEC board in still air.

(4) Human body model, 1.5 kΩ in series with 100 pF.

(5) If Military/Aerospace specified devices are required, contact the Texas Instruments Sales Office/ Distributors for availability and specifications.
