6. NOTES
6.1 Intended use. Microcircuits conforming to this drawing are intended for use for Government microcircuit applications
(original equipment), design applications, and logistics purposes.
6.1.1 Replaceability. Microcircuits covered by this drawing will replace the same generic device covered by a contractor
prepared specification or drawing.
6.1.2 Substitutability. Device class Q devices will replace device class M devices.
6.2 Configuration control of SMD's. All proposed changes to existing SMD's will be coordinated with the users of record for
the individual documents. This coordination will be accomplished using DD Form 1692, Engineering Change Proposal.
6.3 Record of users. Military and industrial users should inform Defense Supply Center Columbus (DSCC) when a system
application requires configuration control and which SMD's are applicable to that system. DSCC will maintain a record of users
and this list will be used for coordination and distribution of changes to the drawings. Users of drawings covering microelectronic
devices (FSC 5962) should contact DSCC-VA, telephone (614) 692-0544.
6.4 Comments. Comments on this drawing should be directed to DSCC-VA , Columbus, Ohio 43218-3990, or telephone
(614) 692-0547.
6.5 Abbreviations, symbols, and definitions. The abbreviations, symbols, and definitions used herein are defined in
MIL-PRF-38535 and MIL-HDBK-1331.
6.5.1 Timing limits. The table of timing values shows either a minimum or a maximum limit for each parameter. Input
requirements are specified from the external system point of view. Thus, address setup time is shown as a minimum
since the system must supply at least that much time (even though most devices do not require it). On the other hand,
responses from the memory are specified from the device point of view. Thus, the access time is shown as a maximum
since the device never provides data later than that time.

6.6 Sources of supply.
6.6.1 Sources of supply for device classes Q and V. Sources of supply for device classes Q and V are listed in QML-38535.
The vendors listed in QML-38535 have submitted a certificate of compliance (see 3.6 herein) to DSCC-VA and have agreed to
this drawing.
6.6.2 Approved sources of supply for device class M. Approved sources of supply for class M are listed in MIL-HDBK-103.
The vendors listed in MIL-HDBK-103 have agreed to this drawing and a certificate of compliance (see 3.6 herein) has been
submitted to and accepted by DSCC-VA.
