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.
SN65C is a Texas Instruments order-code family — not a single orderable MPN. This page lists 27 variants that share the same core device but differ in suffix fields (package, grade, reel/tube, electrical bin, etc.). Pick the exact full part number; substituting within the family without checking the datasheet often causes assembly or spec mismatches.
Quadruple Low-Power Drivers/Receivers 20-PDIP -40 to 85 Other listed variants describe: Dual RS-422 Transceiver, 10Mbps, 5V, 2 Drivers/2 Receivers, TSSOP; Dual Differential Drivers and Receivers With +/-8-kV IEC ESD Protection 16-TSSOP -40 to 85.
Across listed variants, watch these parameters: packages: 28-SOIC (0.295", 7.50mm Width).
Suffix examples in this family: 1154N, 1168EPW, 1168EPWR, 1168ERGYR, 1168N, 1168PWR, 3221PWR, 3222DBR. The characters after the base number usually encode package, temperature, or performance grade — compare the variant table column-by-column rather than assuming pin-compatible drops-in.
Example MPNs: SN65C1154N, SN65C1168EPW, SN65C1168EPWR, SN65C1168ERGYR, SN65C1168N, SN65C1168PWR.
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.
SN65C uses a shared prefix; characters after the prefix encode orderable options. Two lines with the same prefix are not drop-in replacements unless the differing columns match your need.
Suffixes seen here: 1154N, 1168EPW, 1168EPWR, 1168ERGYR, 1168N, 1168PWR, 3221PWR, 3222DBR, 3222EDB, 3222EDBR (+17 more).
Full MPN examples: SN65C1154N, SN65C1168EPW, SN65C1168EPWR, SN65C1168ERGYR, SN65C1168N.
Tip: photograph or copy the reel label — reel diameter, QTY per reel, and moisture sensitivity level (MSL) are often suffix-driven and won't show in the schematic.
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.
