Caution:••••Exceeding absolute maximum ratings shown will damage the device.
The device is static sensitive. Always follow ESD rules when working with the device.
The case temperature of the device shall never exceed +50˚C. Use proper heatsink or fan ifnecessary.
Proper torque, 8.0 ± 0.15 inch-pounds (0.90 ± 0.02 Nm), should be applied. SAGE Millimeter
torque wrench, model SCH-08008-S1, is highly recommended.
