MAX4051AEEE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4051AEEE is a low-voltage, CMOS analog multiplexer featuring eight channels in an 8:1 configuration. It operates on dual supplies from ±2.7V to ±8V or a single supply between +2.7V and +16V. The device handles rail-to-rail analog signals with guaranteed on-resistance of 100Ω at ±5V supplies. Key electrical characteristics include channel-to-channel on-resistance matching of 6Ω maximum, off-leakage current of 0.1nA at +25°C, and TTL/CMOS logic compatibility. It is housed in a 16-pin QSOP package and supports an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'EEE' corresponds to the 16-pin QSOP package and the -40°C to +85°C industrial temperature grade. Confirm that the 'A' designation ensures fully characterized on-resistance match and flatness specifications compared to standard variants. Ensure the source documentation explicitly lists this exact part number as available before proceeding with procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4051AEEE when an 8-channel multiplexer is required with strict requirements for on-resistance matching and low leakage. This variant is suitable for designs needing pin compatibility with legacy 74HC4051 parts while offering improved performance metrics. Verify that the system voltage range falls within the specified single or dual supply limits and that the QSOP footprint fits the PCB layout constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4051/MAX4052/MAX4053 family of low-voltage CMOS analog switches manufactured by Analog Devices / Maxim Integrated. The MAX4051A specifically denotes the 8-channel multiplexer version with enhanced 'A' suffix characterization for resistance matching and leakage. It shares the same functional block and pinout structure as the MAX4052 (dual 4-channel) and MAX4053 (triple SPDT) counterparts within the series.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4051ACSE+ and MAX4051ACEE are alternative packages within the same family. For direct pin-compatible replacement, verify the temperature range and package type match the design requirements.
