(1) 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 under operating conditions is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed.
(3) This value is limited to 1.975 V maximum.

(1) The temperature values fit to JEDEC RAW cards A, B, and C. The user must keep T_case below the specified values in order to keep the
junction temperature below +125°C. Other combinations of features and termination resistors can require lower case temperature and
extra cooling. These combinations depend on the specific application.
