(1) “Absolute Maximum Ratings” are those beyond which the safety of the device cannot be verified. They are not meant to imply that the
device should be operated at these limits. The tables of “Electrical Characteristics” provide conditions for actual device operation.
(2) If Military/Aerospace specified devices are required, please contact the TI Sales Office/Distributors for availability and specifications.
(3) Derate linearly @ 6.11 mW/°C to 400 mW at 70°C.
(4) Derate linearly at 5.56 mW/°C to 650 mW at 70°C.

(1) All currents into device pins are positive; all currents out of device pins are negative. All voltages are referenced to device ground unless
otherwise specified.
(2) All typicals are given for VCC = 5V and TA = 25°C.
(3) All worst case parameters for which this note is applied, must be increased by 10% for DS75176BT. The other parameters remain valid
for −40°C < TA < +85°C.
