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 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:

Coupling transformer turns ratio Device type Generic number Circuit function Transformer Direct Single channel, driver-receiver 01 FC155371 (receiver idle normally low) 1.66:1 1.2:1 02 FC155372 (receiver idle normally high) 1.66:1 1.2:1 03 ARX3420 (receiver idle normally low) 1.41:1 1:1 04 ARX3424 (receiver idle normally high) 1.41:1 1:1 05 NHI-1531 (receiver idle normally low) 1.77:1 1.25:1 06 NHI-1545 (receiver idle normally high) 1.77:1 1.25:1 07 CT1589M (receiver idle normally low) 1.2:1 1:1 08 CT1589I (receiver idle normally high) 1.2:1 1:1

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 appendix C of MIL-M-38510, and as follows:

Outline letter Case outline X See figure 1 (24-lead, 1.40" × .805" × .200") dual-in-line package Y See figure 1 (24-lead, 1.27" × .700" × .215") dual-in-line package (bathtub) U See figure 1 (24-lead, 1.26" × .620" × .200") dual-in-line package T See figure 1 (24-lead, 1.275" × .775" × .175") flat package

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 specification when lead finishes A, B, and C are considered acceptable and interchangeable without preference.
