			MIN	MAX	UNIT
V_CC	Supply voltage		–0.5	6	V
V_I	Input voltage⁽²⁾		–0.5	6	V
V_O	Output voltage ⁽²⁾		–0.5	6	V
I_IK	Input clamp current	V_I < 0		–20	mA
I_OK	Output clamp current	V_O < 0		–20	mA
I_IOK	Input-output clamp current	V_O < 0 or V_O > V_CC		±20	mA
I_OL	Continuous output low current	V_O = 0 to V_CC		50	mA

I_CC	Continuous current through V_CC			160	mA
T_j(MAX)	Maximum junction temperature			100	°C
T_stg	Storage temperature		–65	150	°C

(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

(2) The input negative-voltage and output voltage ratings may be exceeded if the input and output current ratings are observed.

6.2 ESD Ratings

			VALUE	UNIT
V_(ESD)	Electrostatic discharge	Human-body model (HBM), per ANSI/ESDA/JEDEC JS-001 ⁽¹⁾	±2000	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. Manufacturing with less than 500-V HBM is possible with the necessary precautions.

(2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process. Manufacturing with less than 250-V CDM is possible with the necessary precautions.

I_OL	Low-level output current⁽²⁾	INT, SDA	T_j ≤ 100°C		3.5	mA
T_A	Operating free-air temperature			–40	85	°C

(1) For voltages applied above V_CC, an increase in I_CC will result.

(2) The values shown apply to specific junction temperatures, which depend on the R_θJA of the package used. See the Calculating Junction Temperature and Power Dissipation section on how to calculate the junction temperature.
