Link — Ds80249 P Rev 12 Schematic
Finding a direct link to a "Rev 12" schematic specifically can be difficult because manufacturers often consolidate revisions or archive older files. However, here is the best approach to finding the documentation:
1. Texas Instruments Datasheet: Texas Instruments acquired National Semiconductor (the original manufacturer of many Dallas/DS parts). The official datasheet contains the pinout diagrams (which serve as the schematic reference for the chip) and electrical characteristics.
2. Understanding the "P" and "Rev 12":
| Concern | Recommendation | |---------|----------------| | Copyright | The schematic is usually © OEM. Use it only for internal engineering, repair, or as permitted by the OEM’s licensing terms. Do not redistribute the PDF publicly without permission. | | Confidentiality | If the part is used in a regulated product (automotive, medical), the schematic may be classified as “Controlled Technical Information”. Store it on a secure, access‑controlled server. | | Version control | Keep a log (date, person, source URL) of every download. When a newer revision appears (e.g., Rev 13), archive the old file and migrate changes. | | Component obsolescence | Rev 12 may reference parts that are now obsolete. Cross‑reference each component with an “Obsolescence Management” tool (e.g., SiliconExpert) before ordering spares. |
If any of the above mismatches, you are likely looking at an older or unofficial copy.
