MAX4558CSE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4558CSE+T 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 matching of 2Ω typical. Off-leakage current is 1nA max at +25°C. Digital inputs are TTL/CMOS compatible with thresholds of +0.8V to +2.4V. Switching times include turn-on of 150ns and turn-off of 120ns at ±5V. Operating temperature range is 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the C suffix indicates the commercial temperature range of 0°C to +70°C. Confirm the SE suffix corresponds to the 16-pin Narrow SOIC package. Ensure the T suffix denotes tape-and-reel packaging for automated assembly. Check RoHS compliance status indicated by the plus sign. Validate that the specific lot date code meets project requirements.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when pin compatibility with standard logic families is required alongside ESD robustness. Choose for applications needing rail-to-rail signal swing under low voltage conditions. Consider for designs where low leakage and high isolation are critical. Verify supply voltage constraints align with the specified operational range. Ensure thermal management fits within the commercial temperature limits.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4558/MAX4559/MAX4560 family of low-voltage CMOS analog switches. The MAX4558 specifically provides an 8-to-1 multiplexer configuration. It shares the same package and pinout with the dual 4-to-1 MAX4559 and triple SPDT MAX4560 variants. All members offer identical ESD protection characteristics and low-power operation profiles.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct pin-compatible replacements include the MAX4559CSE+T and MAX4560CSE+T from the same family. Standard logic equivalents like the 74HC4051 may be considered if ESD protection levels are not critical. Verify electrical parameters such as on-resistance and leakage against original design specifications before substitution.

Analog Switches, Multiplexers, Demultiplexers FAQ

How does the ESD protection mechanism function?

The device uses on-chip bidirectional silicon-controlled rectifiers (SCRs) between protected pins and ground. These SCRs activate during ESD strikes to bypass surge current safely to ground.

What are the digital input logic thresholds?

All digital inputs have +0.8V to +2.4V logic thresholds, ensuring compatibility with TTL and CMOS logic when using a single +5V supply or dual ±5V supplies.

What happens if an analog signal exceeds the supply rails?

Internal reverse ESD-protection diodes connect each analog signal pin to both VCC and VEE. If a signal exceeds these rails, one of these diodes conducts to clamp the voltage.
