scope:

This drawing forms a part of a one part - one part number documentation system (see 6.6 herein). This drawing describes device requirements for hybrid microcircuits to be processed in accordance with MIL-H-38534. Two product assurance classes, military high reliability (device class H) and space application (device class K) and a choice of case outlines and lead finishes are available and are reflected in the Part of Identifying Number (PIN). When available, a choice of radiation hardness assurance levels are reflected in the PIN.

The PIN shall be as shown in the following example:

Device classes H and K RHA marked devices shall meet the MIL-H-38534 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 Accuracy 01 DSC-11520-112 16-Bit D/S and D/R converter ±8 minutes 02 DSC-11520-113 16-Bit D/S and D/R converter ±4 minutes 03 DSC-11520-114 16-Bit D/S and D/R converter ±2 minutes 04 DSC-11520-115 16-Bit D/S and D/R converter ±1 minutes

This device class designator shall be a single letter identifying the product assurance level as follows:

Device class Device requirements documentation H or K Certification and qualification to MIL-H-38534

The case outline(s) shall be designated in appendix C of MIL-M-38510, as follows:

Outline letter Case outline X See figure 1 (36-lead, 1.900" × .780" × .210"), dual-in-line

The lead finish shall be as specified in MIL-H-38534 for classes H and K. 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.
