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 B, Q, and M) and space application (device classes S and V), and a choice of case outlines and lead finishes are available and are reflected in the Part or Identifying Number (PIN). Device class M microcircuits represent non-JAN class B 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 classes M, B, and S RHA marked devices shall meet the MIL-M-38510 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 26LS31 Quad, high speed, differential line driver 02 26F31 Quad, high speed, differential line driver

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 B or S Certification and qualification to MIL-M-38510 Q or V Certification and qualification to MIL-I-38535

For device classes M, B, and S, case outline(s) shall meet the requirements in appendix C of MIL-M-38510 and as listed below. For device classes Q and V, case outline(s) shall meet the requirements of MIL-I-38535, appendix C of MIL-M-38510, and as listed below.

Outline letter Case outline E D-2 (16-lead, .840" × .310" × .200"), dual-in-line package F F-5 (16-lead, .440" × .285" × .085") flat-package 2 C-2 (20-terminal, .358" × .358" × .100"), square chip carrier package

The lead finish shall be as specified in MIL-M-38510 for classes M, B, and S or MIL-I-38535 or 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.
