ELECTRICAL SPECIFICATIONS
Unless otherwise specified, these specifications apply over VCC=5V, VC=12V and TA=0 to 70°C. Typical values refer
to TA=25°C. Low duty cycle pulse testing is used which keeps junction and case temperatures equal to the ambient
temperature.
ABSOLUTE MAXIMUM RATINGS
VCC Supply Voltage ..................................................
-0.5V - 25V
VC Supply Voltage ....................................................
-0.5V - 25V
Storage Temperature Range ......................................
-65°C To 150°C
Operating Junction Temperature Range .....................
0°C To 125°C
CAUTION: Stresses above those listed in "Absolute Maximum Ratings" may cause permanent damage to the device.
