Absolute Maximums
The Absolute Maximum Ratings specify the worst case conditions that can be applied to the
device. These ratings are not meant as operational specifications, and stresses above the listed
values may cause damage to the device. Specifications are not always stand-alone, that is, the
specification may have other requirements as well.
An example of this is the “maximum current sourced/sunk by any I/O pin”. The number of I/O pins
that can be sinking/sourcing current, at any one time, is dependent upon the maximum current
sunk/source by the port(s) (combined) and the maximum current into the V
V
and internal logic. If these specifications are exceeded, then electromigration may occur on these
Power and Ground buses. Over time electromigration would cause these buses to open (be dis-
connected from the pin), and therefore cause the logic attached to these buses to stop operating.
So exceeding the absolute specifications may cause device reliability issues.
Input Clamp Current is defined as the current through the diode to V
specification.
