MM74HC4052SJX Equivalent & Substitute Parts

Part Overview

The MM74HC4052SJX is a 2-circuit SP4T analog switch IC manufactured by onsemi, designed for signal routing and multiplexing applications. This part operates with single supply voltage (2V to 6V) or dual supply voltage (±2V to 6V), featuring 100Ohm on-state resistance and 4:1 multiplexer/demultiplexer functionality in a 16-SOP package. The product is currently obsolete, making equivalent substitutes necessary for ongoing design support and procurement.

Substitute Part Grouping Explanation

Substitution eligibility for the MM74HC4052SJX is determined by the following core parameters:

Switch circuit type: SP4T (single-pole, four-throw)
Number of circuits: 2
Multiplexer/demultiplexer configuration: 4:1
Package compatibility: 16-SOIC surface mount
Mounting type: Surface mount
Base product number alignment: 74HC4052 or equivalent 4052 series

Substitute parts must maintain the same functional architecture (2-circuit, 4:1 multiplexer configuration) and physical package footprint. Variations in on-state resistance, bandwidth, leakage current, and operating temperature range are acceptable provided the substitute meets or exceeds the application requirements. Supply voltage compatibility must be verified for each application context.

Engineering Selection Recommendations

CD74HC4052NSR (Texas Instruments) is the primary recommended substitute. This part maintains identical supply voltage specifications (2V ~ 6V single, ±1V ~ 5V dual) and package footprint (16-SOIC, 0.209" width) as the MM74HC4052SJX. The on-state resistance increase from 100Ohm to 130Ohm is within acceptable tolerance for most signal routing applications. The CD74HC4052NSR offers superior bandwidth performance (185MHz vs. 35MHz) and is currently in active production status with ROHS3 compliance certification.

HEF4052BT,653 (Nexperia) is an alternative substitute with active product status and ROHS3 compliance. This part features a different package width (0.154" vs. 0.209"), which may require PCB layout verification. The on-state resistance of 155Ohm and reduced bandwidth (70MHz) are acceptable for lower-frequency applications. The extended operating temperature range (-40°C ~ 125°C) provides additional thermal margin compared to the original part.

HEF4052BT,013 (Nexperia) is functionally equivalent to HEF4052BT,653 but carries discontinued status at DiGi Electronics, limiting long-term procurement viability.

For new designs or long-term production requirements, CD74HC4052NSR is the preferred choice due to active manufacturing status and proven supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can I directly replace MM74HC4052SJX with CD74HC4052NSR without PCB modifications?

A: Yes. Both parts use identical 16-SOIC packages with 0.209" width and maintain the same pin configuration. No PCB layout changes are required for direct substitution.

Q: What is the impact of increased on-state resistance in substitute parts?

A: The CD74HC4052NSR (130Ohm) and HEF4052BT variants (155Ohm) have higher on-state resistance than the original MM74HC4052SJX (100Ohm). This increases signal attenuation and may affect applications with high-impedance loads or precision analog signal routing. Verify that your circuit design tolerates the additional resistance before substitution.

Q: Are the Nexperia HEF4052BT variants compatible with the original package footprint?

A: HEF4052BT,653 and HEF4052BT,013 use a narrower 16-SOIC package (0.154" width) compared to the MM74HC4052SJX (0.209" width). While both are 16-SOIC packages, the different widths may not be footprint-compatible. Verify PCB pad spacing before selecting these alternatives.

Q: What are the supply voltage differences between substitutes?

A: The MM74HC4052SJX and CD74HC4052NSR both support single supply (2V ~ 6V) and dual supply (±2V ~ 6V and ±1V ~ 5V respectively). The HEF4052BT variants support only single supply (3V ~ 15V) with no dual supply option. Select based on your circuit's power supply architecture.

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

A: CD74HC4052NSR from Texas Instruments is recommended for long-term designs due to active production status and established supply chain presence. HEF4052BT,653 from Nexperia is also actively manufactured but requires package footprint verification.

Q: Do all substitutes meet RoHS compliance requirements?

A: CD74HC4052NSR, HEF4052BT,013, and HEF4052BT,653 are all ROHS3 compliant. The original MM74HC4052SJX does not specify RoHS status. Verify compliance requirements for your application before final part selection.
