Poelking DEFENSE SUPPLY CENTER COLUMBUS COLUMBUS, OHIO 43218-3990 STANDARD CHECKED BY 1. SCOPE 1.1 Scope. This drawing documents two product assurance class levels consisting of high reliability (device classes 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 are reflected in the PIN. 1.2 PIN. The PIN is as shown in the following examples. For device classes M and Q: 5962 - 89749 01 E A Federal RHA Device Case Lead stock class designator type outline finish designator (see 1.2.1) (see 1.2.2) (see 1.2.4) (see 1.2.5) / / Drawing number For device class V: 5962 F 89749 01 V E 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 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 54AC191 Up/down counter with preset and ripple clock 02 54AC191 Up/down counter with preset and ripple clock 1.2.3 Device class designator. The device class designator is a single letter identifying the product assurance level as listed below. Since the device class designator has been added after the original issuance of this drawing, device classes M and Q designators will not be included in the PIN and will not be marked on the device.
