MAX4781ETE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4781ETE+T is a high-speed, low-voltage CMOS analog multiplexer configured as an 8-channel switch. It operates on a single supply ranging from +1.6V to +3.6V. At a +3V supply, the device features a typical on-resistance of 0.7Ω with 0.3Ω matching between channels and 0.1Ω flatness. The component handles rail-to-rail analog signals while consuming less than 3µW of quiescent power. It supports continuous current handling up to 150mA and offers fast switching times with turn-on at 11ns and turn-off at 4ns. The part is housed in a space-saving 16-pin Thin QFN package measuring 3mm x 3mm.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature range. Ensure compatibility with existing PCB footprints for the 16-pin Thin QFN configuration. Confirm RoHS compliance status through manufacturer certificates prior to integration into final assemblies.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when designing low-voltage systems requiring high-speed analog switching. The 8-channel configuration suits applications needing extensive signal routing within a compact footprint. Consider the 0.7Ω on-resistance for minimal signal attenuation in sensitive audio or data paths.

Analog Switches, Multiplexers, Demultiplexers Part Context

This device belongs to the MAX4781/MAX4782/MAX4783 family of high-speed, low-voltage CMOS analog switches. While the MAX4781 provides an 8-channel multiplexer, the MAX4782 offers two 4-channel multiplexers, and the MAX4783 contains three SPDT switches. All variants share similar electrical characteristics and pinout compatibility.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4781EUE serves as a TSSOP package alternative within the same series. Industry-standard 74HC4051 parts are pin-compatible but differ electrically. Designers should verify functional equivalence before substituting.
