Texas Instruments SN65C
SN65C variants from Texas Instruments
SN65C Overview
What changes between part numbers, and what to check before you lock the BOM — Microcontrollers.
Key Features
- Footprint / package: 28-SOIC (0.295", 7.50mm Width)Single package option across listed variants; still confirm reel vs tube suffix if you auto-insert.
- Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
- 27 distinct suffix patternsExamples: 1154N, 1168EPW, 1168EPWR, 1168ERGYR, 1168N (+22 more). Decode suffix meaning in the ordering notes under the variant table.
Target Applications
- Microcontrollers — design-in and field replacement
- BOM scrub where only the base prefix is known but suffix is TBD
- Second-source checks when the original MPN is constrained

Ordering Code Differences
How suffixes on SN65C map to package, grade, and reel options.
How to Choose the Right SN65C Microcontrollers
Match the footprint first
Packages here: 28-SOIC (0.295", 7.50mm Width). Open the land-pattern drawing before you substitute a different suffix.
Electrical headroom
Compare voltage and current columns in the variant table. For SN65C, a suffix with lower voltage or current rating will not survive the same circuit without recalculation.
Temp grade letter matters
Commercial (0–70 °C) and industrial (−40–85 °C+) suffixes look similar in the prefix — confirm ambient + self-heating, not just the first page of the datasheet.
Copy the full MPN
Do not BOM only "SN65C" — include the full suffix (e.g. 1154N, 1168EPW, 1168EPWR). RFQ with reel/tube preference and required date code.

Frequently Asked Questions
Common technical questions about the SN65C product family.
SN65C is a base / family code from Texas Instruments. You order a full MPN such as SN65C1154N, SN65C1168EPW, SN65C1168EPWR. The variant table lists 27 orderable lines with different suffixes.
Listed suffix fragments include: 1154N, 1168EPW, 1168EPWR, 1168ERGYR, 1168N, 1168PWR. Typically they encode package (28-SOIC (0.295", 7.50mm Width)), temperature grade, and tape/reel option. Always decode on the Texas Instruments datasheet ordering guide — do not guess from pattern alone.
Lifecycle values in our listing: Active. Status is per MPN suffix — one variant can be Active while another is NRND. Check PCN for your exact suffix before multi-year commitments.
Full manufacturer MPN (not just SN65C), quantity, needed date code, reel vs tube, and any compliance docs (CoC, RoHS, conflict minerals). If you only know the base prefix, include a photo of the existing label or reel.
