4.4.1 Group A inspection.
a. Tests shall be as specified in table II herein.
b. CIN, and COUT shall be measured on ly for initial qualification and after process or design changes which may affect
capacitance. CIN and shall be measured bet ween the designated terminal and GND at a frequency of 1 MHz. For CIN,
and COUT, test all applicable pins on five devices with zero failures.
For CIN and COUT, a device manufacturer may qualify devices by functional groups. A specific functional group shall
be composed of function types that by design will yiel d the same capacitance values when tested in accordance with
table I herein. The device manufacturer shall set a functional group limit for the CIN and COUT 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 g uaranteed, if not tested, to the limits and
conditions specified in table I herein. The device manufacturer shall submit to DSCC the device functions listed in
each functional group and the test results for each device tested.
c. For device class M, subgroups 7 and 8 tests shall be sufficient to verify the truth table in figure 2 herein. T he 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 i nclude verifying the functionality of the device.
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 meas ured for the worst case outputs of the device. All other outputs
shall be guaranteed, if not tested, to the limits established f or the worst case outputs. The worst case outputs tested
are to be determined by the manufacturer. T est 5 devices assembled i n the worst case package type supplie d to this
document. All other package t ypes 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 d etermined 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 us ed, 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 shal l then submit to DSCC-VA data from testing on both fixtures, that shall inclu de 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 o utput under test.
For VOHP, VOHV, VOLP, and VOLV, a device manufacturer may qualify devices by functional groups. A specific function al
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 fun ctional group limit for the VOHP, VOHV, VOLP, and VOLV tests.
The device manufacturer may then test one device function from a functional group, to th e limits and conditions
specified herein. All other device functions in that particular functional gro up shall be guaranteed, if not tested, to the
limits and conditions specified in table I, here in. T he device manufacturers shall submit to DSCC-VA the device
functions listed in each functional group and test results, along with the oscilloscop e 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 herei n.
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 re quest. 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 = +125C, minimum.
c. Test duration: 1,000 hours, except as permitted b y method 1005 of MIL-STD-883.
