Texas Instruments SN75ALS
SN75ALS variants from Texas Instruments
SN75ALS Overview
What changes between part numbers, and what to check before you lock the BOM — Drivers, Receivers and Transceivers.
SN75ALS is a Texas Instruments order-code family — not a single orderable MPN. This page lists 43 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: P | Operating Supply Voltage: 5V | Max Supply Voltage: 5.25V | Min Supply Voltage: 4.75V | Output Voltage: 6V | Output Current: 60mA | Number of Channels: 2 | Data Rate: 35Mbps Other listed variants describe: Bus Transceiver, 4-Ch, 5V, 19ns, SOIC, Surface Mount; Dual Differential Drivers And Receivers 16-PDIP 0 to 70.
Across listed variants, watch these parameters: packages: P, 8-DIP (0.300", 7.62mm).
Suffix examples in this family: 176BP, 057DWR, 1177N, 1178N, 1178NSR, 160N, 161DWR, 161N. 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: SN75ALS176BP, SN75ALS057DWR, SN75ALS1177N, SN75ALS1178N, SN75ALS1178NSR, SN75ALS160N.
Key Features
- Footprint / package: P, 8-DIP (0.300", 7.62mm)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.
- 43 distinct suffix patternsExamples: 176BP, 057DWR, 1177N, 1178N, 1178NSR (+38 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

Ordering Code Differences
How suffixes on SN75ALS map to package, grade, and reel options.
SN75ALS 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: 176BP, 057DWR, 1177N, 1178N, 1178NSR, 160N, 161DWR, 161N, 162DWR, 164DWR (+33 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: SN75ALS176BP, SN75ALS057DWR, SN75ALS1177N, SN75ALS1178N, SN75ALS1178NSR.
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 SN75ALS Drivers, Receivers and Transceivers
Match the footprint first
Packages here: P, 8-DIP (0.300", 7.62mm). Open the land-pattern drawing before you substitute a different suffix.
Electrical headroom
Compare voltage and current columns in the variant table. For SN75ALS, 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 "SN75ALS" — include the full suffix (e.g. 176BP, 057DWR, 1177N). RFQ with reel/tube preference and required date code.
