8.1 Absolute Maximum Ratings⁽¹⁾⁽²⁾⁽³⁾

over operating free-air temperature range (unless otherwise noted)

		MIN	MAX	UNIT
Supply voltage	VDD	–0.3	20	V
OUT voltage		–0.3	VDD + 0.3	V
Output continuous current	I_{OUT_DC}(source/sink)		0.3	A
Output pulsed current (0.5 µs)	I_{OUT_pulsed}(source/sink)		4
IN+, IN-⁽⁴⁾, EN		–0.3	20	V
Operating virtual junction temperature, T_J		–40	150	°C
Lead temperature	Soldering, 10 sec.		300
Lead temperature	Reflow		260
Storage temperature, T_stg		–65	150

(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 voltages are with respect to GND unless otherwise noted. Currents are positive into, negative out of the specified terminal. See Packaging Section of the data sheet for thermal limitations and considerations of packages.

(3) These devices are sensitive to electrostatic discharge; follow proper device handling procedures.

(4) Maximum voltage on input pins is not restricted by the voltage on the VDD pin.

8.2 ESD Ratings

			VALUE	UNIT
V_(ESD)	Electrostatic discharge	Human body model (HBM), per ANSI/ESDA/JEDEC JS-001⁽¹⁾	±4000	V
V_(ESD)	Electrostatic discharge	Charged-device model (CDM), per JEDEC specification JESD22-C101⁽²⁾	±1000	V

(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.
