MAX4639EUE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4639EUE+ is a dual 4:1 CMOS analog multiplexer/demultiplexer operating from single +1.8V to +5V or dual ±2.5V supplies. It features a typical on-resistance (RON) of 3.5Ω at +5V and 6Ω at +3V, with a maximum RON match of 0.4Ω between channels. The device offers -75dB off-isolation and -85dB crosstalk, with switching times of 18ns tON and 7ns tOFF. It supports bidirectional operation, rail-to-rail signal handling, and TTL/CMOS logic compatibility in a 16-pin TSSOP package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the ordering suffix EUE+ confirms the 16-pin TSSOP package and lead-free/RoHS compliance. Ensure the temperature range matches the E grade specification (-40°C to +85°C). Confirm that the tape-and-reel designation is not required if bulk packaging is needed, as the datasheet indicates T denotes tape and reel. Cross-reference the manufacturer's current documentation for any pinout or electrical characteristic updates.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual independent 4-channel switching is required within a low-voltage system. The MAX4639 is suitable for applications needing rail-to-rail signal integrity and low charge injection. Compare against the MAX4638 if an 8:1 single mux topology is preferred instead of two 4:1 channels. Consider the 3.5Ω on-resistance impact on signal attenuation for high-impedance sources.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4639EUE+ belongs to the MAX4638/MAX4639 family of low-voltage analog switches manufactured by Maxim Integrated. This series provides CMOS-based multiplexing solutions designed for portable and battery-powered instrumentation. The EUE+ variant specifically denotes the industrial temperature range and TSSOP surface-mount packaging format.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional substitutes include other Maxim Integrated dual 4:1 analog multiplexers such as the MAX4619 or MAX4620 series, provided voltage ranges and on-resistance specifications align with the design requirements. Verify pin compatibility and control logic interfaces before substitution.
