3. REQUIREMENTS
3.1 Qualification. Microcircuits furnished under this specification shall be products that are manufactured by a
manufacturer authorized by the qualifying activity for listing on the applicable qualified manufacturers list before
contract award (see 4.2 and 6.3). When manufacturer programmed devices are delivered to the user, an altered item
drawing shall be prepared by the contracting activity to specify the required program configuration.
3.2 Item requirements. The individual item requirements shall be in accordance with MIL-PRF-38535 and as
specified herein or as modified in the device manufacturer's Quality Management (QM) plan. The modification in the
QM plan shall not affect the form, fit, or function as described herein.
3.3 Design, construction, and physical dimensions. The design, construction, and physical dimensions shall be
as specified in MIL-PRF-38535 and herein.
3.3.1 Terminal connections. The terminal connections shall be as specified on figure 1.
3.3.2 Truth tables.
3.3.2.1 Unprogrammed devices. The truth tables for unprogrammed devices for contracts involving no altered
item drawing shall be as specified on figure 2. When required in groups A, B, or C (see 4.4), the devices shall be
programmed by the manufacturer prior to test. A minimum of 50 percent of the total number of fuses shall be
programmed or at least 25 percent of the total number of fuses to any altered item drawing.
3.3.2.2 Programmed devices. The truth table for programmed devices shall be as specified by the altered item
drawing.
3.3.3 Logic diagrams. The logic diagrams for unprogrammed devices shall be as specified on figure 3.
3.3.4 Case outlines. The case outlines shall be as specified in 1.2.3.
3.4 Lead material and finish. The lead material and finish shall be in accordance with MIL-PRF-38535 (see 6.6).
3.5 Electrical performance characteristics. Unless otherwise specified, the electrical performance characteristics
are as specified in table I, and apply over the full recommended case temperature range.
3.6 Electrical test requirements. Electrical test requirements shall be as specified in table II and (where
applicable), the altered item drawing for the applicable device type and device class. The subgroups of table III which
constitute the minimum electrical test requirements for screening, qualification, and quality conformance, by device
class, are specified in table II.
3.7 Marking. Marking shall be in accordance with MIL-PRF-38535. For programmed devices, the altered item
drawing number shall be added to the marking by the programming activity.
3.8 Processing options. Since the device is capable of being programmed by either the manufacturer or the user
to result in a wide variety of configurations, two processing options are provided for selection in the contract, using an
altered item drawing.
3.8.1 Unprogrammed device delivered to the user. All testing shall be verified through group A testing as defined
in 3.3.2.1, tables II. It is recommended that users perform subgroups 7 and 9 after programming to verify the specific
program configuration.
3.8.2 Manufacturer programmed device delivered to the user. All testing requirements and quality assurance
provisions herein, including the requirements of the altered item drawing, shall be satisfied by the manufacturer prior
to delivery.
3.9 Microcircuit group assignment. The devices covered by this specification shall be in microcircuit group
number 14 (see MIL-PRF-38535, appendix A).
