Electrical and Environmental Specifications
This section contains the electrical and environmental specifications for the IXF440. The IXF440
supports both 5 V and 3.3 V signaling environments for all pins.
8.1
Functional Operating Range
Table 19
lists the functional operating range. Refer to
Section 8.2
for details about the absolute
maximum ratings. The signalling environment for the IX Bus pins are dependent on vdd_clmp.
Table 20
lists the AC parameters for the 3.3 V signaling levels.
Table 21
lists the AC parameters for the 5 V signaling levels.
8.2
Absolute Maximum Rating
Applying stresses beyond the absolute maximum may cause unrecoverable damage to the device.
Operation of this product is not implied for any condition beyond the ranges specified in the
functional operation range described in
Section 8.1
. Operating this product at the absolute
maximum rating for a prolonged period can negatively impact device reliability.
