Texas Instruments SN65EPT
SN65EPT variants from Texas Instruments
SN65EPT Overview
What changes between part numbers, and what to check before you lock the BOM — Translators and Level Shifters.
Key Features
- Footprint / package: VSSOP, SOICLand pattern and thermal pad differ between these packages — run a quick footprint check before you swap variants.
- Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
- 6 distinct suffix patternsExamples: 21DGK, 23D, 21DGKR, 22DGK, 22DR (+1 more). Decode suffix meaning in the ordering notes under the variant table.
Target Applications
- Translators and Level Shifters — 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

How to Choose the Right SN65EPT Translators and Level Shifters
Match the footprint first
Packages here: VSSOP, SOIC. Open the land-pattern drawing before you substitute a different suffix.
Electrical headroom
Compare voltage and current columns in the variant table. For SN65EPT, 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 "SN65EPT" — include the full suffix (e.g. 21DGK, 23D, 21DGKR). RFQ with reel/tube preference and required date code.
