choice of case outlines and lead finishes which 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.

1.2.3 Device class designator. This device class designator shall be a single letter identifying the product assurance level. All
levels are defined by the requirements of MIL-PRF-38534 and require QML Certification as well as qualification (Class H, K, and
E) or QML Listing (Class G and D). The product assurance levels are as follows:
Device class
K
Device performance documentation
Highest reliability class available. This level is intended for use in space
applications.
Standard military quality class level. This level is intended for use in applications
where non-space high reliability devices are required.
Reduced testing version of the standard military quality class. This level uses the
Class H screening and In-Process Inspections with a possible limited temperature
range, manufacturer specified incoming flow, and the manufacturer guarantees (but
may not test) periodic and conformance inspections (Group A, B, C and D).
Designates devices which are based upon one of the other classes (K, H, or G)
with exception(s) taken to the requirements of that class. These exception(s) must
be specified in the device acquisition document; therefore the acquisition document
should be reviewed to ensure that the exception(s) taken will not adversely affect
system performance.
H
G
E
1/
Due to the nature of the 4 transistor design of the die used in these device types, topologically pure testing is important,
particularly for high reliability applications. The device manufacturer should be consulted concerning their testing
methods and algorithms.

accordance with MIL-PRF-38534. Compliance with MIL-PRF-38534 shall include the performance of all tests herein or as
designated in the device manufacturer's Quality Management (QM) plan or as designated for the applicable device class. The
manufacturer may eliminate, modify or optimize the tests and inspections herein, however the performance requirements as
defined in MIL-PRF-38534 shall be met for the applicable device class. In addition, the modification in the QM plan shall not
affect the form, fit, or function of the device for the applicable device class.
3.2 Design, construction, and physical dimensions. The design, construction, and physical dimensions shall be as specified in
MIL-PRF-38534 and herein.
3.2.1 Case outline(s). The case outline(s) shall be in accordance with 1.2.4 herein and figure 1.
3.2.2 Terminal connections. The terminal connections shall be as specified on figure 2.
3.2.3 Truth table(s). The truth table(s) shall be as specified on figure 3.
