______
1/ Stresses above the absolute maximum rating may cause permanent damage to the device. Extended operation at the
maximum levels may degrade performance and affect reliability.
2/ Measurement taken under absolute worst case condition. Data taken with a thermal camera for highest power density
location. See MIL-STD-1835 for average package JC thermal numbers.
3/ External input filtering should be considered to trade off desired dynamic response versus undesired response to system
transients and electromagnetic interference (EMI). Refer to paragraph 6.7 for more information.
