4.4.1 Group A inspection.
a. Tests shall be as specified in table IIA herein.
b. For device class M, subgroups 7 and 8 tests shall be sufficient to verify the truth table in figure 2 herein. The test
vectors used to verify the truth table shall, at a minimum, test all functions of each input and output. All possible input
to output logic patterns per function shall be guaranteed, if not tested, to the truth table in figure 2, herein. For device
classes Q and V, subgroups 7 and 8 shall include verifying the functionality of the device.
c. CIN and CPD shall be measured only for initial qualification and after process or design changes which may affect
capacitance. CIN shall be measured between the designated terminal and GND at a frequency of 1 MHz. CPD shall be
tested in accordance with the latest revision of JEDEC Standard No. 20 and table IA herein. For CIN and CPD, test all
applicable pins on five devices with zero failures.
4.4.2 Group C inspection. The group C inspection end-point electrical parameters shall be as specified in table IIA herein.
4.4.2.1 Additional criteria for device class M. Steady-state life test conditions, method 1005 of MIL-STD-883:
a. Test condition A, B, C, or D. The test circuit shall be maintained by the manufacturer under document revision level
control and shall be made available to the preparing or acquiring activity upon request. The test circuit shall specify
the inputs, outputs, biases, and power dissipation, as applicable, in accordance with the intent specified in test method
1005 of MIL-STD-883.
b. TA = +125°C, minimum.
c. Test duration: 1,000 hours, except as permitted by method 1005 of MIL-STD-883.
4.4.2.2 Additional criteria for device classes Q and V. The steady-state life test duration, test condition and test temperature,
or approved alternatives shall be as specified in the device manufacturer's QM plan in accordance with MIL-PRF-38535. The
test circuit shall be maintained under document revision level control by the device manufacturer's TRB in accordance with
MIL-PRF-38535 and shall be made available to the acquiring or preparing activity upon request. The test circuit shall specify the
inputs, outputs, biases, and power dissipation, as applicable, in accordance with the intent specified in test method 1005 of
MIL-STD-883.
4.4.3 Group D inspection. The group D inspection end-point electrical parameters shall be as specified in table IIA herein.
4.4.4 Group E inspection. Group E inspection is required only for parts intended to be marked as radiation hardness assured
(see 3.5 herein).
a. End-point electrical parameters shall be as specified in table IIA herein.
b. For device classes Q and V, the devices or test vehicle shall be subjected to radiation hardness assured tests as
specified in MIL-PRF-38535 for the RHA level being tested. For device class M, the devices shall be subjected to
radiation hardness assured tests as specified in MIL-PRF-38535, appendix A for the RHA level being tested. All device
classes must meet the post irradiation end-point electrical parameter limits as defined in table IA at
T
A = +25°C +5°C, after exposure, to the subgroups specified in table IIA herein.
4.4.4.1 Total dose irradiation testing. Total dose irradiation testing shall be performed in accordance with MIL-STD-883
method 1019, condition A, and as specified herein.
4.4.4.1.1 Accelerated annealing test. Accelerated annealing tests shall be performed on all devices requiring a RHA level
greater than 5k rads (Si). The post-anneal end-point electrical parameter limits shall be as specified in table IA herein and shall
be the pre-irradiation end-point electrical parameter limit at 25°C ±5°C. Testing shall be performed at initial qualification and
after any design or process changes which may affect the RHA response of the device.
4.4.4.2 Single event phenomena (SEP). When specified in the purchase order or contract, SEP testing shall be required on
class V devices. SEP testing shall be performed on the Standard Evaluation Circuit (SEC) or alternate SEP test vehicle as
approved by the qualifying activity at initial qualification and after any design or process changes which may affect the upset or
latchup characteristics. Test four devices with zero failures. ASTM F1192 may be used as a guideline when performing SEP
testing. The test conditions for SEP are as follows:
a. The ion beam angle of incidence shall be between normal to the die surface and 60° to the normal, inclusive
(i.e. 0° ≤ angle ≤ 60°). No shadowing of the ion beam due to fixturing or package related effects is allowed.
b. The fluence shall be ≥ 100 errors or ≥ 107 ions/cm2.
c. The flux shall be between 102 and 105 ions/cm2/s. The cross-section shall be verified to be flux independent by
measuring the cross-section at two flux rates which differ by at least an order of magnitude.
d. The particle range shall be ≥ 20 microns in silicon.
