74AC11257 Overview

What changes between part numbers, and what to check before you lock the BOM — Signal Switches, Multiplexers and Decoders.

Key Features

Footprint / package: PDIP, TSSOPLand 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.
2 distinct suffix patternsExamples: N, PW. Decode suffix meaning in the ordering notes under the variant table.

Target Applications

Signal Switches, Multiplexers and Decoders — 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 Variants

Compare 2 74AC11257 part numbers by package, electrical parameters, lifecycle, and availability. Use RFQ for stock and lead-time confirmation.

Part Number	Description	Package Type	Manufacturer	Lifecycle	RoHS	Availability	Action

How to Choose the Right 74AC11257 Signal Switches, Multiplexers and Decoders

📦

Match the footprint first

Packages here: PDIP, TSSOP. Open the land-pattern drawing before you substitute a different suffix.

⚡

Electrical headroom

Compare voltage and current columns in the variant table. For 74AC11257, 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 "74AC11257" — include the full suffix (e.g. N, PW). RFQ with reel/tube preference and required date code.

Frequently Asked Questions

Common technical questions about the 74AC11257 product family.

Is 74AC11257 a single part I can order, or a family prefix?

74AC11257 is a base / family code from Texas Instruments. You order a full MPN such as 74AC11257N, 74AC11257PW. The variant table lists 2 orderable lines with different suffixes.

What do the suffix letters on 74AC11257 part numbers mean?

Listed suffix fragments include: N, PW. Typically they encode package (PDIP, TSSOP), temperature grade, and tape/reel option. Always decode on the Texas Instruments datasheet ordering guide — do not guess from pattern alone.

Which specs actually differ between 74AC11257 variants here?

On this page the varying fields are: Package Type. Filter the table by the parameter you care about before picking an MPN.

Can I swap between PDIP, TSSOP packages in the same 74AC11257 family?

Only after footprint and thermal review. Packages listed here (PDIP, TSSOP) use different land patterns and often different thermal resistance. Layout swaps need a new paste stencil at minimum, not just a BOM edit.

What is the lifecycle status of 74AC11257 variants?

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.

What should I send for an RFQ on 74AC11257?

Full manufacturer MPN (not just 74AC11257), 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.
