8.1 Absolute Maximum Ratings

over operating free-air temperature range (unless otherwise noted)⁽¹⁾⁽²⁾⁽³⁾

		MIN	MAX	UNIT
Supply voltage	VDD	–0.3	20	V
OUT voltage	DC	–0.3	VDD + 0.3	V
OUT voltage	Repetitive pulse less than 200 ns⁽⁵⁾	–2	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
Input voltage	IN+, IN-⁽⁴⁾	–6	20	V
Operating virtual junction temperature, T_J		–40	150	°C
Lead temperature	Soldering, 10 sec.		300	°C
Lead temperature	Reflow		260	°C
Storage temperature, T_stg		–65	150	°C

(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 datasheet 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.

(5) Values are verified by characterization on bench.

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.

8.3 Recommended Operating Conditions

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

	MIN	TYP	MAX	UNIT
Supply voltage, V_DD	4.5	12	18	V

Input voltage, IN+ and IN-	0		18	V

8.4 Thermal Information

		5 PINS
R_θJA	Junction-to-ambient thermal resistance	217.6	°C/W
R_θJC(top)	Junction-to-case (top) thermal resistance	85.8	°C/W
R_θJB	Junction-to-board thermal resistance	44	°C/W
ψ_JT	Junction-to-top characterization parameter	4	°C/W
ψ_JB	Junction-to-board characterization parameter	43.2	°C/W

(1) For more information about traditional and new thermal metrics, see the Semiconductor and IC Package Thermal Metrics application report, SPRA953.

(2) Under identical power dissipation conditions, the DRS package will allow to maintain a lower die temperature than the DBV. θ_JA metric should be used for comparison of power dissipation capability between different packages (Refer to the Application Information section).
