PRODUCTION DATA

4.1 Absolute Maximum Ratings

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

			MIN	MAX	UNIT
V_CC	Supply voltage range		–0.5	6.5	V
V_I	Input voltage range⁽¹⁾		–0.5	6.5	V
V_O	Output voltage range⁽¹⁾⁽²⁾		–0.5	V_CC + 0.5	V
I_IK	Input clamp current	V_I < 0		–50	mA
I_OK	Output clamp current	V_O < 0		–50	mA
I_O	Continuous output current			±50	mA
	Continuous current through V_CC or GND			±100	mA
T_stg	Storage temperature range		–65	150	°C
P_tot	Power dissipation⁽³⁾⁽⁴⁾	T_A = –40°C to 125°C		500	mW

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

(3) The value of V_CC is provided in the recommended operating conditions table.

(4) For the D package, above 70°C the value of P_tot derates linearly with 8 mW/K.

(5) For the DB, NS, and PW packages, above 60°C the value of P_tot derates linearly with 5.5 mW/K.
