MM74HC4052WM Equivalent & Substitute Parts

Part Overview

The MM74HC4052WM is a 2-circuit IC switch with SP4T (single-pole, 4-throw) configuration and 4:1 multiplexer/demultiplexer functionality manufactured by onsemi. This component operates across a supply voltage range of 2V to 6V (single supply) or ±2V to 6V (dual supply) and features 100Ohm on-state resistance with 35MHz bandwidth. The part is classified as obsolete, making equivalent substitutes necessary for new designs and ongoing production support.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MM74HC4052WM is determined by the following critical parameters:

• Switch Circuit Configuration: SP4T topology with 4:1 multiplexer/demultiplexer function
• Circuit Count: 2 independent circuits per package
• On-State Resistance: Maximum 100Ohm specification
• Supply Voltage Compatibility: Minimum support for 2V ~ 6V single supply or ±2V ~ 6V dual supply
• Package Type: 16-SOIC form factor with 0.295" (7.50mm) width
• Mounting: Surface mount technology

Substitute parts are grouped into two categories based on these parameters:

Category A - Direct Functional Equivalents (onsemi MC74HC4052 Series)

• MC74HC4052ADWG and MC74HC4052ADWR2G maintain identical electrical specifications with enhanced performance characteristics
• Both support the full voltage range and maintain 100Ohm on-state resistance
• Available in active product status with RoHS3 compliance

Category B - Functional Alternatives (Nexperia HEF4052 Series)

• HEF4052BT,013 and HEF4052BT,653 provide SP4T 4:1 switching with 2-circuit configuration
• Higher on-state resistance (155Ohm maximum) and extended supply voltage range (3V ~ 15V single supply)
• Different package width specification (0.154", 3.90mm) requires PCB layout verification

Engineering Selection Recommendations

For Direct Replacement (Recommended Primary Path)

MC74HC4052ADWR2G is the preferred substitute. This part maintains identical electrical specifications to the MM74HC4052WM while offering active product status, ensuring long-term availability and supply chain stability. The part is RoHS3 compliant and REACH unaffected. The identical package footprint (16-SOIC, 0.295" width) eliminates PCB redesign requirements. Enhanced performance characteristics (95MHz bandwidth, -60dB crosstalk, 10Ohm channel matching) provide design margin without compromising compatibility.

MC74HC4052ADWG provides equivalent functionality with obsolete product status. Use this part only when MC74HC4052ADWR2G availability is constrained. Both onsemi variants are packaged identically and electrically interchangeable.

For Extended Temperature or Supply Voltage Range Applications

HEF4052BT,653 is suitable when applications require extended operating temperature range (-40°C to 125°C) or higher supply voltage tolerance (3V ~ 15V single supply). This Nexperia part is active and RoHS3 compliant. The 155Ohm on-state resistance and different package width (0.154", 3.90mm) require circuit validation and PCB layout modification. Dual supply operation is not supported.

HEF4052BT,013 offers identical electrical performance to HEF4052BT,653 but carries discontinued status. Avoid this part for new designs.

Frequently Asked Questions (FAQ)

Q: Can MC74HC4052ADWR2G directly replace MM74HC4052WM without circuit modification?

A: Yes. Both parts share identical on-state resistance (100Ohm), supply voltage ranges (2V ~ 6V single, ±2V ~ 6V dual), package footprint (16-SOIC, 0.295" width), and circuit configuration (SP4T, 4:1, 2 circuits). No schematic or PCB changes are required. The MC74HC4052ADWR2G offers superior performance characteristics and active product status.

Q: What is the impact of higher on-state resistance in HEF4052BT parts?

A: The HEF4052BT series specifies 155Ohm maximum on-state resistance compared to 100Ohm for the MM74HC4052WM. This 55Ohm difference increases signal attenuation and power dissipation in switching applications. Applications with low-impedance signal sources or tight attenuation budgets require circuit analysis before substitution.

Q: Are the onsemi MC74HC4052 variants pin-compatible with the original MM74HC4052WM?

A: Yes. Both MC74HC4052ADWG and MC74HC4052ADWR2G maintain identical 16-SOIC pinout and package dimensions (0.295", 7.50mm width). Direct socket substitution is possible without PCB modification.

Q: Why do HEF4052BT parts have a different package width specification?

A: The HEF4052BT series uses a 16-SOIC package with 0.154" (3.90mm) width, while the MM74HC4052WM and MC74HC4052 variants use 0.295" (7.50mm) width. This dimensional difference requires PCB footprint verification and potential layout adjustment. Pin pitch and lead spacing remain compatible with standard 16-SOIC land patterns, but physical clearance around the component must be confirmed.

Q: Which substitute part offers the best long-term availability?

A: MC74HC4052ADWR2G carries active product status from onsemi and is available in Tape & Reel packaging, indicating ongoing production and distribution support. HEF4052BT,653 is also active from Nexperia. Both parts are suitable for new designs requiring extended component lifecycle support.

Q: Can HEF4052BT parts operate with dual supply voltages?

A: No. The HEF4052BT series supports single supply operation only (3V ~ 15V). The MM74HC4052WM and MC74HC4052 variants support both single supply (2V ~ 6V) and dual supply (±2V ~ 6V) configurations. Applications requiring dual supply operation must use onsemi MC74HC4052 parts.
