(1) Stresses beyond those listed under Absolute Maximum Ratings table may cause permanent damage to the device. These are stress
ratings only, and functional operation of the device at these or any other conditions beyond those indicated under Recommended
Operating Conditions table are not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device
reliability.
(2) All voltage values are with respect to network ground terminal.
(3) The reference regulator may be bypassed for operation from a fixed 5-V supply by connecting the VCC and reference output (REF
OUT) pin both to the supply voltage. In this configuration, the maximum supply voltage is 6 V.
7.2 ESD Ratings
VALUE UNIT
Human body model (HBM), per ANSI/ESDA/JEDEC JS-001, all

C101, all pins
(2)
(1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process.
(2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process.
7.3 Recommended Operating Conditions

θJA
Junction-to-ambient thermal resistance
(2)(3)

(1) For more information about traditional and new thermal metrics, see the IC Package Thermal Metrics application report, SPRA953.
(2) Maximum power dissipation is a function of T
J
(max), θJA, and T
A
. The maximum allowable power dissipation at any allowable ambient
temperature is PD = (TJ(max) – TA)/θJA. Operation at the absolute maximum TJ of 150°C can impact reliability.
(3) The package thermal impedance is calculated in accordance with JESD 51-7.
