1. SCOPE
1.1 Scope. This drawing documents two product assurance class levels consisting of high reliability (device class Q and M)
and space application (device class V). 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 (RHA) levels is reflected in the PIN.
1.2 PIN. The PIN is as shown in the following example:

1.2.1 RHA designator. Device classes Q and V RHA marked devices meet the MIL-PRF-38535 specified RHA levels and are
marked with the appropriate RHA designator. Device class M RHA marked devices meet the MIL-PRF-38535, appendix A
specified RHA levels and are marked with the appropriate RHA designator. A dash (-) indicates a non-RHA device.
1.2.2 Device type(s). The device type(s) identify the circuit function as follows:
