MAX4531EPP

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4531EPP is a low-voltage CMOS analog multiplexer switch configured as two independent 4-channel muxes. It operates from single supplies of +2V to +12V or dual supplies of ±2V to ±6V. The device features on-resistance up to 150Ω max, with channel matching within 8Ω max and flatness of 10Ω max. Switching times are 150ns (Ton) and 120ns (Toff) at ±4.5V. Off-leakage current is 1nA at +25°C and 50nA at +85°C. It includes address latching, two enable inputs, and 2kV ESD protection. Operating temperature range is -40°C to +85°C in a 20-pin Plastic DIP package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'EPP' indicates the extended temperature range (-40°C to +85°C) and 20-pin Plastic DIP package configuration. Confirm that the ordering information matches the manufacturer's current datasheet revision, as component availability and packaging options may change over time without notice.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part when dual 4-channel multiplexing is required with TTL/CMOS compatibility. Ensure supply voltage requirements align with the +2V to +12V single or ±2V to ±6V dual supply ranges. Consider the 150Ω maximum on-resistance and 150ns switching speed for system timing constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4531 belongs to the MAX4530/MAX4531/MAX4532 family of low-voltage CMOS analog switches. While the MAX4530 provides an 8-channel mux and the MAX4532 offers three SPDT switches, the MAX4531 specifically integrates two 4-channel muxes. All devices share pin compatibility and core architectural features.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct substitutes include other MAX4531 variants such as MAX4531CWP or MAX4531EAP, provided the package type and temperature range meet design requirements. Verify pinout and electrical specifications against the target application before substitution.

Analog Switches, Multiplexers, Demultiplexers FAQ

How does the MAX4531 handle analog signals relative to its power supply?

The device supports rail-to-rail signal handling, allowing analog signals to swing from V- to V+.

What is the logic input threshold compatibility?

Digital inputs have 0.8V and 2.4V logic thresholds, ensuring compatibility with both TTL and CMOS logic levels when using ±5V or a single +5V supply.

Does the MAX4531 support break-before-make switching?

Yes, the device features a break-before-make interval to prevent short circuits during channel transitions.
