scope:
This drawing forms a part of a one part - one part number documentation system (see 6.6 herein). Two product assurance classes consisting of military high reliability (device classes Q and M) and space application (device class V), and a choice of case outlines and lead finishes are available and are reflected in the Part or Identifying Number (PIN). Device class N microcircuits represent non-JAN class 8 microcircuits in accordance with 1.2.1 of MIL-STD-883, "Provisions for the use of MIL-STD-883 in conjunction with compliant non-JAN devices". When available, a choice of Radiation Hardness Assurance (RHA) levels are reflected in the PIN.
The PIN shall be as shown in the following example:
Device class M RHA marked devices shall meet the MIL-I-38535 appendix A specified RHA levels and shall be marked with the appropriate RHA designator. Device classes Q and V RHA marked devices shall meet the MIL-I-38535 specified RHA levels and shall be marked with the appropriate RHA designator. A dash (-) indicates a non-RHA device.
The device type(s) shall identify the circuit function as follows:
Device type Generic number Circuit function 01 LM1575-ADJ Positive, adjustable, step-down switching voltage regulator 02 LM1575HVADJ Positive, adjustable, step-down switching voltage regulator, high voltage
The device class designator shall be a single letter identifying the product assurance level as follows:
Device class Device requirements documentation M Vendor self-certification to the requirements for non-JAN class B microcircuits in accordance with 1.2.1 of MIL-STD-883 Q or V Certification and qualification to MIL-I-38535
The case outline(s) shall be as designated in MIL-STD-1835 and as follows:
Outline letter Descriptive designator Terminals Package style E GDIP1-Tl6 or CDIP2-Tl6 16 Dual-in-line X See figure 1 4. Can Y See figure 1 5 Flange mount
The lead finish shall be as specified in MIL-STD-883 (see 3.1 herein) for class M or MIL-I-38535 for classes Q and V. Finish letter "X" shall not be marked on the microcircuit or its packaging. The "X" designation is for use in specifications when lead finishes A, B, and C are considered acceptable and interchangeable without preference.
