Texas Instruments SN75LBC
SN75LBC variants from Texas Instruments
SN75LBC Overview
What changes between part numbers, and what to check before you lock the BOM — Drivers, Receivers and Transceivers.
Key Features
- Footprint / package: SOIC, 16-DIP (0.300", 7.62mm), 8-SOIC (0.154", 3.90mm Width)Land 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.
- 36 distinct suffix patternsExamples: 184D, 031D, 170DB, 170DBR, 172A16DWR (+31 more). Decode suffix meaning in the ordering notes under the variant table.
Target Applications
- Drivers, Receivers and Transceivers — 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 SN75LBC Drivers, Receivers and Transceivers
Match the footprint first
Packages here: SOIC, 16-DIP (0.300", 7.62mm), 8-SOIC (0.154", 3.90mm Width). Open the land-pattern drawing before you substitute a different suffix.
Electrical headroom
Compare voltage and current columns in the variant table. For SN75LBC, 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 "SN75LBC" — include the full suffix (e.g. 184D, 031D, 170DB). RFQ with reel/tube preference and required date code.
