4.4.1 Group A inspection.
a. Tests shall be as specified in table II herein.
b. For device class M, subgroups 7 and 8 tests shall be sufficient to verify the truth table. For device classes Q and V,
subgroups 7 and 8 shall include verifying the functionality of the device.
c. CIN and CI/O shall be measured only for initial qualification and after process or design changes which may affect
capacitance. CIN and CI/O shall be measured between the designated terminal and GND at a frequency of 1 MHz. This
test may be performed at 10 MHz and guaranteed, if not tested, at 1 MHz. The DC bias for the pin under test (VBIAS) =
2.5 V or 3.0 V. For CIN and CI/O, test all applicable pins on five devices with zero failures.
For CIN and CI/O, a device manufacturer may qualify devices by functional groups. A specific functional group shall be
composed of function types, that by design, will yield the same capacitance values when tested in accordance with
table I, herein. The device manufacturer shall set a function group limit for the CIN and CI/O tests. The device
manufacturer may then test one device functional group, to the limits and conditions specified herein. All other device
functions in that particular functional group shall be guaranteed, if not tested, to the limits and test conditions specified
in table I, herein. The device manufacturers shall submit to DSCC-VA the device functions listed in each functional
group and the test results for each device tested.
d. Ground and VCC bounce tests are required for all device classes. These tests shall be performed only for initial
qualification, after process or design changes which may affect the performance of the device, and any changes to the
test fixture. VOLP, VOLV, VOHP, and VOHV shall be measured for the worst case outputs of the device. All other outputs
shall be guaranteed, if not tested, to the limits established for the worst case outputs. The worst case outputs tested
are to be determined by the manufacturer. Test 5 devices assembled in the worst case package type supplied to this
document. All other package types shall be guaranteed, if not tested, to the limits established for the worst case
package. The 5 devices to be tested shall be the worst case device type supplied to this drawing. All other device
types shall be guaranteed, if not tested, to the limits established for the worst case device type. The package type and
device type to be tested shall be determined by the manufacturer. The device manufacturer will submit to DSCC-VA
data that shall include all measured peak values for each device tested and detailed oscilloscope plots for each VOLP,
VOLV, VOHP, and VOHV from one sample part per function. The plot shall contain the waveforms of both a switching
output and the output under test.
Each device manufacturer shall test product on the fixtures they currently use. When a new fixture is used, the device
manufacturer shall inform DSCC-VA of this change and test the 5 devices on both the new and old test fixtures. The
device manufacturer shall then submit to DSCC-VA data from testing on both fixtures, that shall include all measured
peak values for each device tested and detailed oscilloscope plots for each VOLP, VOLV, VOHP, and VOHV from one
sample part per function. The plot shall contain the waveforms of both a switching output and the output under test.
For VOHP, VOHV, VOLP, and VOLV, a device manufacturer may qualify devices by functional groups. A specific functional
group shall be composed of function types, that by design, will yield the same test values when tested in accordance
with table I, herein. The device manufacturer shall set a functional group limit for the VOHP, VOHV, VOLP, and VOLV tests.
The device manufacturer may then test one device function from a functional group, to the limits and conditions
specified herein. All other device functions in that particular functional group shall be guaranteed, if not tested, to the
limits and conditions specified in table I, herein. The device manufacturers shall submit to DSCC-VA the device
functions listed in each functional group and test results, along with the oscilloscope plots, for each device tested.
4.4.2 Group C inspection. The group C inspection end-point electrical parameters shall be as specified in table II 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 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.
