MAX4559ESE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4559ESE is a low-voltage, CMOS analog multiplexer configured as a dual 4-to-1 switch. It operates from dual supplies of ±2V to ±6V or a single +2V to +12V supply. The device features ±15kV ESD protection on signal pins and guarantees an on-resistance of 160Ω at ±5V and 220Ω at +5V. It offers 1nA off-leakage current at +25°C, TTL/CMOS-compatible logic inputs, and break-before-make switching. Packaged in a 16-pin Narrow SOIC with an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Dual 4-to-1 multiplexer architecture providing independent X and Y channel routing
• Integrated ±15kV electrostatic discharge protection on all analog signal pins
• Rail-to-Rail analog signal handling capability across the full supply voltage range
• TTL and CMOS logic compatibility for direct interfacing with standard digital controllers

Analog Switches, Multiplexers, Demultiplexers Applications

• Battery-operated equipment requiring low power consumption
• Audio and video signal routing systems
• Low-voltage data-acquisition systems
• Communications circuits in high-ESD environments

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'E' confirms the industrial temperature range (-40°C to +85°C) and 'SE' indicates the 16-pin Narrow SOIC package. Confirm RoHS compliance status via the manufacturer's ordering information table, as '+' suffixes denote lead-free packaging. Ensure design margins account for the absolute maximum ratings regarding continuous current limits into any terminal.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a dual 4-to-1 multiplexing function is required within a single package. Verify that the system supply voltage falls within the +2V to +12V single-supply or ±2V to ±6V dual-supply range. Consider the 160Ω on-resistance specification at ±5V for signal integrity requirements. Ensure the application environment does not exceed the specified operating temperature limits for the 'E' grade variant.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4559ESE belongs to the MAX4558/MAX4559/MAX4560 family of low-voltage CMOS analog switches. While the MAX4558 provides an 8-to-1 multiplexer and the MAX4560 offers triple SPDT switches, the MAX4559 specifically addresses applications needing two independent 4-to-1 channels. All members share identical pinouts and ESD protection characteristics, facilitating flexible design choices based on channel count requirements.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct pin-compatible replacements include the industry-standard 74HC4051, 74HC4052, and 74HC4053 series. Note that these discrete logic alternatives lack the integrated ±15kV ESD protection found in the MAX4559 and may require additional circuitry for robust operation in harsh environments.
