(1) Absolute Maximum Ratings indicate limits beyond which 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 absolute maximum specification applies to DC voltage. An extended negative voltage limit of -2V applies for a pulse of up to 1µs,
and -1V for a pulse of up to 20µs.
(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 2.6W is determined using T
A
= 25°C, θ
JA
= 38°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. The machine model is a 200pF
capacitor discharged directly into each pin. The charged device model is per JESD22-C101-C.
Operating Ratings
(1)
Operating Junction Temp. −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. 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) 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.
