Texas Instruments SN74AC
SN74AC variants from Texas Instruments
SN74AC Overview
What changes between part numbers, and what to check before you lock the BOM — Buffers, Drivers, Receivers and Transceivers.
Key Features
- Footprint / package: PDIP, SOIC, TSSOP, SSOP (+2 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.
- 94 distinct suffix patternsExamples: 374N, 564DWR, 74MDREP, 00NE4, 00PW (+89 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 SN74AC map to package, grade, and reel options.
How to Choose the Right SN74AC Buffers, Drivers, Receivers and Transceivers
Match the footprint first
Packages here: PDIP, SOIC, TSSOP, SSOP (+2 more). Open the land-pattern drawing before you substitute a different suffix.
Electrical headroom
Compare voltage and current columns in the variant table. For SN74AC, 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 "SN74AC" — include the full suffix (e.g. 374N, 564DWR, 74MDREP). RFQ with reel/tube preference and required date code.

Frequently Asked Questions
Common technical questions about the SN74AC product family.
SN74AC is a base / family code from Texas Instruments. You order a full MPN such as SN74AC374N, SN74AC564DWR, SN74AC74MDREP. The variant table lists 94 orderable lines with different suffixes.
Listed suffix fragments include: 374N, 564DWR, 74MDREP, 00NE4, 00PW, 14D. Typically they encode package (PDIP, SOIC, TSSOP, SSOP (+2 more)), temperature grade, and tape/reel option. Always decode on the Texas Instruments datasheet ordering guide — do not guess from pattern alone.
On this page the varying fields are: Package Type. Filter the table by the parameter you care about before picking an MPN.
Only after footprint and thermal review. Packages listed here (PDIP, SOIC, TSSOP, SSOP (+2 more)) use different land patterns and often different thermal resistance. Layout swaps need a new paste stencil at minimum, not just a BOM edit.
Lifecycle values in our listing: Active. Status is per MPN suffix — one variant can be Active while another is NRND. Check PCN for your exact suffix before multi-year commitments.
Full manufacturer MPN (not just SN74AC), quantity, needed date code, reel vs tube, and any compliance docs (CoC, RoHS, conflict minerals). If you only know the base prefix, include a photo of the existing label or reel.
Use the datasheet link in the page header. Cross-check electrical curves (SOA, saturation voltage, etc.) against your operating point — the table summarizes order codes, not every graph in the PDF.
