(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) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/Distributors for availability and
specifications.
(3) The absolute maximum specification applies to DC voltage. An extended negative voltage limit of -3V applies for a pulse of up to 200
ns, and -6V for a pulse of up to 50 ns.
(4) The maximum allowable power dissipation is a function of the maximum junction temperature, T
J_MAX
, the junction-to-ambient thermal
resistance, θ
JA
, and the ambient temperature, T
A
. The maximum allowable power dissipation at any ambient temperature is calculated
using: P
D_MAX
= (T
J_MAX
- T
A
) /θ
JA
. The maximum power dissipation of 3.1W is determined using T
A
= 25°C, θ
JA
= 32°C/W, and T
J_MAX
= 125°C.
(5) The human body model is a 100 pF capacitor discharged through a 1.5 kΩ resistor into each pin.
Operating Ratings
(1)
Operating Junction Temperature −40°C to 125°C
Supply Voltage
(2)
3.0V to 38V
(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) Below 4.0V input, power dissipation may increase due to increased R
DS(ON)
. Therefore, a minimum input voltage of 4.0V is required to
operate continuously within specification. A minimum of 3.9V (typical) is also required for startup.
