ELECTRICAL SPECIFICATIONS
Table 5. Absolute Maximum Ratings
(refer to Notes 1 and 2)
Symbol
Notes: 1. Referenced to Vss. Stresses above those listed under “absolute Maximum Ratings” may cause permanent damage to the device.
This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the
operation sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may
affect the device reliability.
2. A dedicated 3.3 V power supply is needed for 3.3 V inputs and outputs.

Notes: 1. Commercial, Industrial, and Military Conditions.
2. Mandatory for 3.3 V buffers only.
3. 3 V buffer specifications are not applicable for main supply below 2.25 V.
4. All circuits will operate to full specifications with a junction temperature of -40 to +125 degrees centigrade. These junction temper-
atures are compatible with the Commercial and Industrial Temperature Ranges.
5. All circuits will be functional from -55 to +150 degrees centigrade junction temperature (military Ambient Temperature Range) but
will not necessary operate to published specifications. Only circuits specified as operational to extended temperature range may
be used when operating to Military temperature conditions.
