Absolute maximums are stress ratings. Exposure of devices to greater than any of these
conditions may adversely affect long-term reliability. Proper operation under conditions
other than those listed in the Performance/Functional Speci?cations Table is not implied or
recommended.
CAUTION: This product is not internally fused. To comply with safety agency certi?cations
and to avoid injury to personnel or equipment, the user must supply an external fast-blow
fuse to the input terminals.
