Storage Temperature Range .............................-65°C to +150°C
Note 1: This device is constructed using a unique set of packaging techniques that impose a limit on the thermal profile to which the
device can be exposed during board-level solder attach and rework. The limit permits the use of only the solder profiles rec-
ommended in the industry-standard specification, JEDEC 020A, paragraph 7.6, Table 3 for IR/VPR and Convection reflow.
Preheating is required. Hand or wave soldering is not allowed.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
