NOTES
1. Exceeding these ratings may cause permanent
damage. Functional operation under these conditions
is not implied.
2. Maximum dissipation should not be exceeded for
more than 1 second, only one output to be tested at
any one time.
3. Exposure to absolute maximum ratings for extended
periods may affect device reliablity.
4. Current is defined as negative into the device.
5. The
θ
data assumes that heat is extracted from the
top of the package.
6. Maximum junction temperature, T
JMAX
, is specified
with power applied.
PDSP16256 MC AC1R and PDSP16256 MC GC1R
(MIL-STD-883 PARTS)
Polyimide is used as an inter-layer dielectric as
glassification. Polymeric material meeting the
requirements of MIL-STD-883 test method 5011 is used
for die attach.
Life tesst/burn-in connections are given in Tables 9 and
10 on the following pages.
Change Notification
The change notification requirements of MIL-PRF-38535
will be implemented on MIL-STD-883 grade devices.
Known customers will be notified of any changes since
the last buy when ordering further parts if significant
changes have been made.
