MAX4558EEE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4558EEE+ 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. Key electrical parameters include a maximum on-resistance of 350Ω at +5V single supply (220Ω typical) and 450Ω at +3V. Off-leakage current is typically 1nA at +25°C. Switching times are up to 300ns turn-on and 200ns turn-off under single-supply conditions.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'EEE+' corresponds to the industrial temperature range (-40°C to +85°C) and the 16-pin QSOP package configuration. Confirm RoHS compliance status through official manufacturer documentation, as ordering suffixes may indicate environmental certifications without altering functional specifications. Ensure the source document explicitly lists this part number variant.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when an 8-channel multiplexer is required within a compact surface-mount footprint. The extended temperature range makes it suitable for industrial applications where ambient conditions exceed commercial limits. Evaluate the on-resistance flatness and leakage current requirements against the specific signal integrity needs of the target circuit design.

Analog Switches, Multiplexers, Demultiplexers Part Context

This device belongs to the MAX4558/MAX4559/MAX4560 family of low-voltage CMOS analog switches manufactured by Analog Devices / Maxim Integrated. The MAX4558 specifically provides an 8-to-1 multiplexing function, distinguishing it from the dual 4-to-1 MAX4559 and triple SPDT MAX4560 variants within the same pinout architecture.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The datasheet confirms pin compatibility with industry-standard 74HC4051 devices. Designers replacing legacy discrete solutions or older multiplexer families should verify that the voltage thresholds and drive currents meet the system requirements.
