MAXIMUM RATINGS (TA = + 25°C, unless otherwise noted)

Rating	Symbol	Value	Unit
Power Supply Voltage	VCC	10	Vdc
Input Voltage Range	VIR	± 30	Vdc
Output Load Current	IL	20	mA
Power Dissipation (Package Limitation, SOIC−14 and Plastic Dual In−Line Package)	PD	1000	mW
Derate above TA = + 25°C	1/ JA	6.7	mW/°C
Operating Ambient Temperature Range	TA	0 to + 75	°C
Storage Temperature Range	Tstg	− 65 to + 175	°C

Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied, damage may occur and reliability may be affected.
