MAX4052EEE+ Equivalent & Substitute Parts

Part Overview

The MAX4052EEE+ is a dual SP4T analog switch IC manufactured by Analog Devices Inc./Maxim Integrated, designed for signal routing and multiplexing applications. This 16-QSOP surface mount device provides two independent 4:1 switch circuits with 100Ohm on-state resistance and operates across a wide supply voltage range of 2V to 16V (single supply) or ±2.7V to ±8V (dual supply). The part is currently in active production status with 973 units in stock. Equivalent and substitute parts are necessary when the primary part becomes unavailable, when alternative packaging formats are required, or when design specifications allow for compatible alternatives with different electrical characteristics.

Substitute Part Grouping Explanation

Substitution eligibility for the MAX4052EEE+ is determined by the following critical parameters:

Switch circuit topology: SP4T configuration with 4:1 multiplexing capability
Dual circuit count: Two independent switch circuits per package
On-state resistance: Maximum 100Ohm (allows higher values in substitutes if application permits)
Supply voltage compatibility: Single supply 2V ~ 16V or dual supply ±2.7V ~ ±8V
Package form factor: 16-pin surface mount (QSOP or TSSOP variants acceptable)
Surface mount compatibility: QSOP and TSSOP packages are mechanically compatible
Compliance requirements: ROHS3 compliance and MSL Level 1

The substitute parts CD74HC4052PWRG4 and CD74HC4052PWT are functionally equivalent dual SP4T 4:1 switch ICs from Texas Instruments. While these parts exhibit higher on-state resistance (130Ohm vs. 100Ohm) and different leakage characteristics, they maintain the same circuit topology, pin count, and core switching functionality. Both substitute parts are available in 16-TSSOP packaging, which is mechanically compatible with the original 16-QSOP package.

Engineering Selection Recommendations

The MAX4052EEE+ remains the preferred choice for new designs due to its active production status and superior electrical characteristics, including lower on-state resistance (100Ohm vs. 130Ohm) and significantly lower leakage current (1nA vs. 200nA).

CD74HC4052PWRG4 is classified as obsolete and should not be selected for new production designs. This part is suitable only for legacy system maintenance or repair applications where exact form factor matching is not critical.

CD74HC4052PWT carries a Last Time Buy status, indicating limited future availability. This part may be considered for applications where the higher on-state resistance and leakage current are acceptable within design margins, and where the narrower supply voltage range (2V ~ 6V single supply, ±1V ~ 5V dual supply) meets application requirements. The extended operating temperature range (-55°C ~ 125°C) provides advantage in extreme temperature environments compared to the MAX4052EEE+ (-40°C ~ 85°C).

All three parts maintain ROHS3 compliance and MSL Level 1 moisture sensitivity rating. Pin-to-pin compatibility exists across all variants, though package dimensions differ slightly between QSOP and TSSOP formats.

Frequently Asked Questions (FAQ)

Q: Can CD74HC4052PWRG4 or CD74HC4052PWT be used as direct replacements for MAX4052EEE+ in existing designs?

A: Both Texas Instruments parts are functionally equivalent in terms of circuit topology and pin configuration. However, the higher on-state resistance (130Ohm vs. 100Ohm) and significantly higher leakage current (200nA vs. 1nA) may impact signal integrity in precision analog applications. The narrower supply voltage range (2V ~ 6V vs. 2V ~ 16V) must be verified against your application requirements. Electrical characterization testing is necessary to confirm compatibility within your specific circuit design.

Q: What are the package compatibility considerations?

A: The MAX4052EEE+ uses 16-QSOP packaging (0.154" width), while both substitute parts use 16-TSSOP packaging (0.173" width). Both are 16-pin surface mount packages with identical pin assignments. PCB footprint modifications may be required due to the 0.019" width difference. Consult package datasheets for precise land pattern specifications before layout finalization.

Q: Why do the substitute parts have higher on-state resistance?

A: The CD74HC4052 series from Texas Instruments uses different semiconductor process technology compared to the MAX4052 series from Analog Devices. This results in different electrical characteristics. The 30Ohm increase in on-state resistance is a fundamental characteristic of the CMOS process used in the 74HC4052 family.

Q: Are there supply voltage limitations with the substitute parts?

A: Yes. The CD74HC4052PWRG4 and CD74HC4052PWT are limited to 2V ~ 6V single supply operation, compared to the MAX4052EEE+ which operates from 2V ~ 16V. Applications requiring supply voltages above 6V cannot use these substitutes. Dual supply operation is limited to ±1V ~ 5V versus ±2.7V ~ 8V for the original part.

Q: What is the significance of the product status differences?

A: MAX4052EEE+ is in active production with ongoing manufacturer support. CD74HC4052PWRG4 is obsolete with no future availability. CD74HC4052PWT is Last Time Buy, meaning the manufacturer will produce a final quantity before discontinuation. For new designs, MAX4052EEE+ is the only recommended choice. Substitutes should be considered only for legacy system support or when supply constraints make alternatives necessary.

Q: How do leakage current differences affect circuit performance?

A: The MAX4052EEE+ exhibits 1nA maximum leakage current, while substitutes exhibit 200nA maximum. In high-impedance signal paths or precision measurement circuits, this 200x difference may introduce unacceptable signal degradation. Applications with lower impedance requirements or where leakage current is not a critical parameter may tolerate the higher leakage of substitute parts.
