Texas Instruments SN74CBT
SN74CBT variants from Texas Instruments
SN74CBT Overview
What changes between part numbers, and what to check before you lock the BOM — Buffers, Drivers, Receivers and Transceivers.
SN74CBT is a Texas Instruments order-code family — not a single orderable MPN. This page lists 113 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.
Package: SOIC | Operating Supply Voltage: 5V | Max Supply Voltage: 5.5V | Min Supply Voltage: 4V | Output Current: 64mA | Number of Channels: 4 | Number of Bits: 4 | Max Operating Temp: 85°C Other listed variants describe: Package: SSOP | Operating Supply Voltage: 5V | Max Supply Voltage: 5.5V | Min Supply Voltage: 4V | Number of Channels: 16 | Number of Outputs: 16 | Number of Bits: 32 | Logic Function: Multiplexer, Demultiplexer; Package: SOT-23-5 | Operating Supply Voltage: 5V | Max Supply Voltage: 5.5V | Min Supply Voltage: 4V | Output Current: 64mA | Number of Channels: 1 | Number of Bits: 1 | Logic Function: Multiplexer, Demultiplexer.
Across listed variants, watch these parameters: packages: SOIC, SSOP, SOT-23-5, TSSOP, 56-BSSOP (0.295", 7.50mm Width) (+3 more).
Suffix examples in this family: 3125CD, 16232DL, 1G125DBVR, 3251DBR, 3257CPW, 3257DBQRG4, 16209ADGVR, 16209ADLR. 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.
Columns that actually vary on this page: Package Type. If two rows match on MPN prefix but differ there, they are not interchangeable for production.
Example MPNs: SN74CBT3125CD, SN74CBT16232DL, SN74CBT1G125DBVR, SN74CBT3251DBR, SN74CBT3257CPW, SN74CBT3257DBQRG4.
Key Features
- Footprint / package: SOIC, SSOP, SOT-23-5, TSSOP (+4 more)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.
- 113 distinct suffix patternsExamples: 3125CD, 16232DL, 1G125DBVR, 3251DBR, 3257CPW (+108 more). Decode suffix meaning in the ordering notes under the variant table.
Target Applications
- Buffers, 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

Ordering Code Differences
How suffixes on SN74CBT map to package, grade, and reel options.
SN74CBT 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: 3125CD, 16232DL, 1G125DBVR, 3251DBR, 3257CPW, 3257DBQRG4, 16209ADGVR, 16209ADLR, 16210DGVR, 16210DLR (+103 more).
What changes between rows: Package Type. Sort the table by these columns when narrowing from base number to a single MPN.
Full MPN examples: SN74CBT3125CD, SN74CBT16232DL, SN74CBT1G125DBVR, SN74CBT3251DBR, SN74CBT3257CPW.
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 SN74CBT Buffers, Drivers, Receivers and Transceivers
Match the footprint first
Packages here: SOIC, SSOP, SOT-23-5, TSSOP (+4 more). Open the land-pattern drawing before you substitute a different suffix.
Electrical headroom
Compare voltage and current columns in the variant table. For SN74CBT, 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 "SN74CBT" — include the full suffix (e.g. 3125CD, 16232DL, 1G125DBVR). RFQ with reel/tube preference and required date code.
