MAX4558ESE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4558ESE is a low-voltage CMOS analog multiplexer configured as an 8-to-1 switch in a 16-pin Narrow SO package. It operates from dual supplies of ±2V to ±6V or a single supply of +2V to +12V, supporting Rail-to-Rail analog signals. The device features guaranteed on-resistance of 160Ω at ±5V and 220Ω at +5V, with channel-to-channel matching of 2Ω typical. Off-leakage current is 1nA max at +25°C. Digital inputs have +0.8V to +2.4V thresholds for TTL/CMOS compatibility. Switching times are 150ns turn-on and 120ns turn-off typical. It includes ±15kV ESD protection on signal pins.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Integrated electrostatic discharge (ESD) protection on all analog input and output pins using on-chip bidirectional silicon-controlled rectifiers.
• TTL and CMOS logic compatible digital inputs that ensure reliable switching across standard voltage levels without external level shifting.
• Rail-to-Rail analog signal handling capability allowing full dynamic range operation within the power supply limits.
• Pin-compatible design with industry-standard 74HC4051 devices to facilitate direct upgrades in existing circuit layouts.

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 operating in high-ESD environments

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm temperature range and packaging details. The 'E' suffix indicates an industrial temperature range of -40°C to +85°C. Ensure the package type matches the intended PCB footprint requirements before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when an 8-to-1 multiplexing function is required with low leakage and high ESD robustness. Verify that the system supply voltage falls within the specified operational range. Consider the on-resistance variation with signal voltage if precise linearity is critical for the application.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4558/MAX4559/MAX4560 family of low-voltage CMOS analog switches manufactured by Analog Devices Inc./Maxim Integrated. The MAX4558 specifically provides an 8-to-1 multiplexer configuration, distinguishing it from the dual 4-to-1 multiplexer (MAX4559) and triple SPDT switch (MAX4560) variants within the same series.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4558CSE is a commercial grade variant with a 0°C to +70°C temperature range. The MAX4558EEE offers the same electrical specifications but in a QSOP package. Direct pin-for-pin replacements must match the 16-pin Narrow SO package and industrial temperature rating.
