Analog Devices MAX4581
MAX4581 variants from Analog Devices
MAX4581 Overview
What changes between part numbers, and what to check before you lock the BOM — Analog Switches, Multiplexers and Demultiplexers.
Key Features
- Footprint / package: 16-SOIC (0.154", 3.90mm Width), 16-VQFN Exposed PadLand 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: ASE+T, EGE+T. Decode suffix meaning in the ordering notes under the variant table.
Target Applications
- Analog Switches, Multiplexers and Demultiplexers — 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 MAX4581 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 |
|---|---|---|---|---|---|---|---|
| MAX4581ASE+T | Package: 16-SOIC (0.154", 3.90mm Width) | Mounting Type: Surface Mount | Operating Temperature: -40°C ~ 125°C (TA) | Supplier Device Package: 16-SOIC | Number of Circuits: 1 | Multiplexer Demultiplexer Circuit: 8:1 | 16-SOIC (0.154", 3.90mm Width) | Analog Devices | Active | Compliant | In Stock | |
| MAX4581EGE+T | Package: 16-VQFN Exposed Pad | Mounting Type: Surface Mount | Operating Temperature: -40°C ~ 85°C (TA) | Supplier Device Package: 16-QFN (4x4) | Number of Circuits: 1 | Multiplexer Demultiplexer Circuit: 8:1 | 16-VQFN Exposed Pad | Analog Devices | Active | Compliant | In Stock |

How to Choose the Right MAX4581 Analog Switches, Multiplexers and Demultiplexers
Match the footprint first
Packages here: 16-SOIC (0.154", 3.90mm Width), 16-VQFN Exposed Pad. Open the land-pattern drawing before you substitute a different suffix.
Electrical headroom
Compare voltage and current columns in the variant table. For MAX4581, 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 "MAX4581" — include the full suffix (e.g. ASE+T, EGE+T). RFQ with reel/tube preference and required date code.
