Gauder DEFENSE SUPPLY CENTER COLUMBUS COLUMBUS, OHIO 43218-3990 CHECKED BY STANDARD 1. SCOPE 1.1 Scope. This drawing documents two product assurance class levels consisting of high reliability (device classes B, Q, and M) and space application (device classes S and 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: 5962 R 90985 01 S R A Federal RHA Device Device Case Lead stock class designator type class outline finish designator (see 1.2.1) (see 1.2.2) designator (see 1.2.4) (see 1.2.5) / (see 1.2.3) / Drawing number 1.2.1 RHA designator. Device classes B, S, 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: Device type Generic number Circuit function 01 54AC521 8-bit magnitude comparator with enable 02 54AC11521 8-bit magnitude comparator with enable 03 54AC521 Radiation hardened 8-bit magnitude comparator with enable 1.2.3 Device class designator. The device class designator is a single letter identifying the product assurance level as follows: Device class Device requirements documentation M Vendor self-certification to the requirements for MIL-STD-883 compliant, non-JAN class level B microcircuits in accordance with MIL-PRF-38535, appendix A B, S, Q, or V Certification and qualification to MIL-PRF-38535 1.2.4 Case outline(s). The case outline(s) are as designated in MIL-STD-1835 and as follows: Outline letter Descriptive designator Terminals Package style R GDIP1-T20 or CDIP2-T20 20 Dual-in-line S GDFP2-F20 or CDFP3-F20 20 Flat pack X See figure 1 20 Flat pack 2 CQCC1-N20 20 Leadless chip carrier 1.2.5 Lead finish. The lead finish is as specified in MIL-PRF-38535 for device classes B, S, Q, and V or MIL-PRF-38535, appendix A for device class M.
