MAX4581EPE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4581EPE is a low-voltage CMOS analog multiplexer switch IC manufactured by Analog Devices Inc./Maxim Integrated. It features an 8:1 configuration with eight input channels and one common output, housed in a 16-pin PDIP package. The device operates on a single supply voltage ranging from 2V to 12V or dual supplies of ±2V to ±6V. Key electrical specifications include a maximum on-resistance of 80 ohms, a channel-to-channel matching of 1 ohm, and a leakage current of 1nA maximum. Switching times are characterized by a maximum turn-on time of 200ns and a turn-off time of 100ns.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Provides high-density signal routing through an 8:1 multiplexing architecture within a compact 16-pin DIP footprint.
• Ensures signal integrity with low on-resistance and tight channel-to-channel matching for precision applications.
• Supports flexible power configurations with operation across wide single and dual supply voltage ranges.

Analog Switches, Multiplexers, Demultiplexers Applications

• Data acquisition systems requiring multi-channel signal selection
• Programmable gain amplifiers and instrumentation circuits
• Automated test equipment signal routing

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix EPE confirms the PDIP-16 package and commercial temperature range during sourcing. Confirm RoHS compliance status as indicated by the plus sign in related variants like MAX4581EPE+. Check manufacturer documentation for any product change notices or end-of-life announcements affecting this specific part number before finalizing procurement plans.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4581EPE when an 8:1 multiplexer topology is required in a through-hole DIP package. Ensure the application voltage stays within the 2V to 12V single supply limit. Compare on-resistance and leakage requirements against other series members if higher performance is needed, noting that this device offers a balance of density and standard packaging for general-purpose switching.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4581-83 family of low-voltage CMOS analog switches. The MAX4581 specifically provides 8:1 multiplexing, distinguishing it from the MAX4582 (4:1) and MAX4583 (3x SPDT). The EPE suffix denotes the industrial/commercial grade PDIP-16 package, differentiating it from TSSOP or SOIC variants which offer smaller footprints but different thermal and mechanical characteristics.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct replacements include other MAX4581 variants with different packages such as MAX4581EUE+ (TSSOP) or MAX4581ETE+ (TQFN), provided pin compatibility and thermal management allow. Verify that substitute parts maintain the same 80-ohm on-resistance and voltage ratings.
