(1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Electrical specifications do not apply when
operating the device beyond its rated operating conditions.
(2) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/Distributors for availability and
specifications.
(3) The maximum power dissipation must be derated at elevated temperatures and is dictated by T
JMAX
(Maximum junction temperature),
θ
JA
(junction to ambient thermal resistance), and T
A
(ambient temperature). The maximum allowable power dissipation at any
temperature is P
DMAX
= (T
JMAX
− T
A
)/θ
JA
or the number given in the Absolute Maximum Ratings, which ever is lower. θ
JA
= 150°C/W.
Operating Ratings
Supply Voltage Range 2.7V to 5.5V
Operating Ambient Range −40°C to 85°C
Operating Junction Temperature Range −40°C to 125°C
Storage Temperature Range −65°C to +150°C
Lead Temperature (Soldering, 5 seconds) 260°C
ESD Rating
(1)
2kV
ESD Rating Output Only 8kV
(1) The human body model is a 100 pF capacitor discharged through a 1.5 kΩ resistor into each pin. Enable pin ESD threshold is 1.7kV.
