(1) Stresses beyond those listed under Absolute Maximum Ratings 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 is 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.

7.2 ESD Ratings

V(ESD) Electrostatic discharge Human-body model (HBM), per AEC Q100-002(1) ±2000 V
Charged-device model (CDM), per AEC Q100-011 ±1000
(1) AEC Q100-002 indicates that HBM stressing shall be in accordance with the ANSI/ESDA/JEDEC JS-001 specification.

7.3 Recommended Operating Conditions

MIN MAX UNIT
VIN1,2 Input voltage range 0.8 VBIAS V
VBIAS Bias voltage range 2.5 5.5 V
VON1,2 ON voltage range 0 5.5 V
VOUT1,2 Output voltage range VIN V
VIH, ON1,2 High-level input voltage, ON1,2 VBIAS = 2.5 to 5.5 V 1.2 5.5 V

TA Operating free-air temperature (2) –40 125 °C
(2) In applications where high power dissipation and/or poor package thermal resistance is present, the maximum ambient temperature may have to be derated. Maximum ambient temperature [TA(max)] is dependent on the maximum operating junction temperature [TJ(max)], the maximum power dissipation of the device in the application [PD(max)], and the junction-to-ambient thermal resistance of the part/package in the application (RθJA), as given by the following equation: TA(max) = TJ(max) – (RθJA × PD(max)).
