C3–C1, E0, E1, CHCLK
Maximum power dissipation (see note) ....... T
Note: Thermal limiting circuitry on-chip will shut down the
circuit at a junction temperature of about 165 C. The de-
vice should never be exposed to this temperature. Opera-
tion above 145 C junction temperature may degrade
device reliability. See the SLIC Packaging Considerations
for more information.
Stresses above those listed under Absolute Maximum Ratings
may cause permanent device failure. Functionality at or above
these limits is not implied. Exposure to Absolute Maximum
Ratings for extended periods may affect device reliability.

Operating Ranges define those limits between which device
functionality is guaranteed.
* Functionality of the device from 0 C to +70 C is guaranteed
by production testing. Performance from –40 C to +85 C is
guaranteed by characterization and periodic sampling of
production units.
