MAX4558CEE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4558CEE is a low-voltage CMOS analog multiplexer configured as an 8-to-1 switch in a 16-pin QSOP 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 ±15kV ESD protection and TTL/CMOS-compatible digital inputs. Electrical characteristics include a maximum on-resistance of 350Ω at +5V single supply (typical 220Ω) and 160Ω at ±5V dual supply. Off-leakage current is typically 1nA at +25°C. Switching times are specified with a typical turn-on time of 250ns and turn-off time of 150ns under single-supply conditions.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CEE' corresponds to the 16-pin QSOP package and the commercial temperature range of 0°C to +70°C. Confirm RoHS compliance status through official documentation, as ordering suffixes may indicate environmental variations. Ensure the source provides valid traceability for this Analog Devices component.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4558CEE when an 8-channel multiplexer is required within a compact QSOP footprint. This variant is suitable for commercial applications where the 0°C to +70°C temperature range meets system requirements. Consider the MAX4558EEE if industrial temperature operation down to -40°C is necessary.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4558 is part of the MAX4558/MAX4559/MAX4560 family of low-voltage CMOS analog switches manufactured by Analog Devices. While the MAX4559 offers dual 4-to-1 configurations and the MAX4560 provides triple SPDT switches, the MAX4558 specifically delivers a single 8-to-1 multiplexer topology.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4558CEE is pin-compatible with the industry-standard 74HC4051 multiplexer. Designers replacing legacy components should verify that the higher ESD protection levels and specific leakage characteristics of the MAX4558 do not conflict with existing circuit constraints.

Analog Switches, Multiplexers, Demultiplexers FAQ

How does the MAX4558 handle overvoltage events?

The device utilizes on-chip bidirectional silicon-controlled rectifiers (SCRs) between the protected X, Y, Z pins and ground. These SCRs activate during ESD strikes to bypass surge current safely to ground without damaging the internal circuitry.

What are the digital input logic thresholds?

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

What is the behavior of the SCRs after an ESD event?

Once triggered by an ESD strike, the SCRs remain latched until the current flowing through them drops below the holding current. System designs must limit connected source currents to ensure the SCRs turn off and normal operation resumes.
