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 or 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 Accuracy type Generic number Circuit function Frequency ±1 LSB 01 SD-14550DX-112 11.8 V S/D converter 400 Hz 4 min 02 SD-14551DX-112 11.8 V R/D converter 400 Hz 4 min 03 SD-14550DX-114 11.8 V S/D converter 400 Hz 2 min 04 SD-14551DX-114 11.8 V R/D converter 400 Hz 2 min 05 SD-14551DX-601 6.8 V R/D converter 400 Hz 2 min

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 as designated in MIL-STD-1835 and as follows:

Outline letter Descriptive designator Terminals Package style X See figure 1 34 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.
