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 on 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. It offers low off-leakage current (1nA max at +25°C) and high off-isolation (-96dB). Digital inputs are TTL/CMOS compatible, and the component provides robust ESD protection up to ±15kV.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'E' confirms the -40°C to +85°C industrial temperature range and 'SE' indicates the 16-pin Narrow SOIC package. Confirm RoHS compliance status via the '+' designation. Ensure the ordering quantity matches the manufacturer's standard tube packaging requirements for this specific part number.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4558ESE+ when an 8-to-1 multiplexing configuration is required within a 16-pin footprint. This model is suitable for applications needing Rail-to-Rail signal swing and robust ESD protection. Compare against the MAX4559 for dual 4-to-1 or MAX4560 for triple SPDT configurations if the pinout remains constant but switching topology differs.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4558 belongs to the MAX4558/MAX4559/MAX4560 family of low-voltage CMOS analog switches manufactured by Analog Devices/Maxim Integrated. These devices share identical pinouts and physical dimensions, differing only in internal switching architecture. The family is designed to replace industry-standard 74HC4051/4052/4053 components while offering superior leakage and ESD performance.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct pin-compatible replacements include the MAX4559ESE+ (dual 4-to-1 mux) and MAX4560ESE+ (triple SPDT switch). Verify that the alternative device's on-resistance and leakage specifications meet the circuit requirements before substitution.

Analog Switches, Multiplexers, Demultiplexers FAQ

How does the ESD protection mechanism function during a strike?

The device utilizes on-chip bidirectional silicon-controlled rectifiers (SCRs) between the protected I/O pins and ground. During an ESD event, these SCRs turn on rapidly to bypass surge current safely to ground, preventing latchup or damage.

What are the logic voltage thresholds for TTL/CMOS compatibility?

All digital inputs have logic thresholds ranging from +0.8V to +2.4V. This ensures compatibility with TTL and CMOS logic levels when operating with a single +5V supply or dual ±5V supplies.

What happens to the switches if an SCR latches due to ESD?

When one or more SCRs turn on due to an ESD event, all switches in the part automatically turn off to prevent current through the active switches from sustaining the latchup condition until the current falls below the holding threshold.
