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 M) 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 [B bar][I bar][T bar]/VEL 01 SDC14613-112 14-bit, 2 V direct resolver converter 400 Hz 4 min VEL 02 SDC14613T-112 14-bit, 2 V direct resolver converter 400 Hz 4 min [B bar][I bar][T bar] 03 SDC14618-112 16-bit, 2 V direct resolver converter 400 Hz 4 min VEL 04 SDC14618T-112 16-bit, 2 V direct resolver converter 400 Hz 4 min [B bar][I bar][T bar] 05 SDC1418-114 16-bit, 2 V direct resolver converter 400 Hz 2 min VEL 06 SDC14618T-114 16-bit, 2 V direct resolver converter 400 Hz 2 min [B bar][I bar][T bar]
This device class designator shall be a single letter identifying the product assurance level as follows:
Device class Device requirements documentation M 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 36 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.
