(1) All voltages are measured with respect to GND, unless otherwise specified.
(2) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for
which the device is functional, but do not ensured specific performance limits. For ensured specifications and test conditions, see the
Electrical Characteristics. The specified specifications apply only for the test conditions listed. Some performance characteristics may
degrade when the device is not operated under the listed test conditions.
(3) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/Distributors for availability and
specifications.
(4) If the input voltage at any pin exceeds the power supply ( that is, VIN < GND or VIN > V
+
) but is less than the absolute maximum
ratings, then the current at that pin should be limited to 5mA. The 30 mA maximum package input current rating limits the number of
pins that can safely exceed the power supply with an input current of 5mA to six pins. Parasitic components and/or ESD protection
circuitry are shown in the Pin Descriptions table.
(5) The maximum power dissipation must be derated at elevated temperatures and is dictated by T
JMAX
, θ
JA
and the ambient temperature,
T
A
. The maximum allowable power dissipation at any temperature is P
D
= (T
JMAX
− T
A
) / θ
JA
.
(6) Human body model (HBM) is a charged 100pF capacitor discharged into a 1.5kΩ resistor. Machine model (MM) is a charged 200pF
capacitor discharged directly into each pin. Charged Device Model (CDM) simulates a pin slowly acquiring charge (such as from a
device sliding down the feeder in an automated assembler) then rapidly being discharged.
