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.
Note 1:
The MAX6477
–
MAX6484 are constructed using a unique set of packaging techniques that impose a limit on the thermal pro-
file the devices can be exposed to during board-level solder attach and rework. This limit permits only the use of the solder
profiles recommended in the industry-standard specification, JEDEC 020A, paragraph 7.6, Table 3 for IR/VPR and
Convection reflow. Pre-heating is required. Hand or wave soldering is not allowed.
