Absolute Maximum Ratings
Table 6-1
absolute maximum and minimum is neither implied nor guaranteed. Functional operating
parameters are listed in the DC characteristics tables.
Stressing the device beyond the “Absolute Maximum Ratings” may cause permanent damage.
These are stress ratings only. Operating beyond the “operating conditions” is not recommended and
extended exposure beyond “operating conditions” may affect reliability.
Thermal Characteristics
The GMCH is designed for operation at die temperatures between 0 °C and 97 °C. The thermal
resistance of the package is given in
