CD4052BCMX Equivalent & Substitute Parts

Part Overview

The CD4052BCMX is a 2-circuit IC switch with SP4T (single-pole, 4-throw) configuration and 4:1 multiplexer/demultiplexer functionality manufactured by onsemi. This interface component operates across a wide supply voltage range (5V to 15V single supply, or ±2.5V to ±7.5V dual supply) and features 240Ohm on-state resistance with 40MHz bandwidth. The part is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production requirements.

Substitute Part Grouping Explanation

Substitution for the CD4052BCMX is determined by the following critical parameters:

Primary Substitution Criteria:

Switch circuit type (SP4T configuration required)
Multiplexer/demultiplexer circuit (4:1 functionality)
Number of circuits (2 circuits)
Package type (16-SOIC form factor)
Operating temperature range (-55°C ~ 125°C)
Mounting type (Surface Mount)

Secondary Compatibility Parameters:

On-state resistance (240Ohm nominal; substitutes with lower resistance values are acceptable for lower signal loss)
Supply voltage compatibility (single supply 5V ~ 15V or dual supply ±2.5V ~ 7.5V)
Bandwidth performance (40MHz minimum)
Leakage current specifications

Engineering Selection Recommendations

For Direct Replacement (Recommended):

Select from the SP4T 4:1 configuration substitutes when the application requires identical switch topology and multiplexer functionality. All recommended substitutes are active products with ROHS3 compliance and REACH unaffected status.

MC74HC4052ADG / MC74HC4052ADR2G: Select when supply voltage range 2V ~ 6V is compatible with your application. These parts offer improved bandwidth (95MHz) and lower on-state resistance (100Ohm) compared to the CD4052BCMX. Suitable for applications requiring higher frequency performance.

MC74LVX4052DG / MC74LVX4052DR2G / MC74LVXT4052DR2G: Select when lowest on-state resistance (26Ohm) is required to minimize signal loss. Supply voltage range 2.5V ~ 6V. Bandwidth of 80MHz is adequate for most analog switching applications. Charge injection specification (12pC) is provided for precision applications.

MC74VHC4052DR2G: Select for applications requiring 2V ~ 6V supply compatibility with 95MHz bandwidth and 100Ohm on-state resistance. Available in Tape & Reel packaging for high-volume production.

74HC4052D,653 / 74HCT4052D,118 (Nexperia): Select when highest bandwidth performance (180MHz) is required. 74HC4052D,653 supports 2V ~ 10V single supply. 74HCT4052D,118 is optimized for 5V TTL-compatible applications (4.5V ~ 5.5V). Operating temperature range limited to -40°C ~ 125°C.

For Alternative Configuration (Limited Compatibility):

MC14052BDG / MC14052BDR2G offer DP4T 2:4 topology with wider supply voltage range (3V ~ 18V single supply). These parts are functionally different and suitable only when DP4T switching configuration is acceptable. Lower bandwidth (17MHz) and higher on-state resistance (280Ohm) limit use to lower-frequency applications.

Frequently Asked Questions (FAQ)

Q: Can I use MC74HC4052ADG as a direct replacement for CD4052BCMX?

A: MC74HC4052ADG is functionally equivalent in switch topology (SP4T 4:1) and package (16-SOIC). However, the supply voltage range differs: MC74HC4052ADG operates at 2V ~ 6V, while CD4052BCMX operates at 5V ~ 15V. Verify your application's supply voltage is within 2V ~ 6V before substitution. The lower on-state resistance (100Ohm vs. 240Ohm) and higher bandwidth (95MHz vs. 40MHz) are performance improvements.

Q: What is the difference between MC74LVX4052DG and MC74LVXT4052DR2G?

A: Both parts are electrically identical with SP4T 4:1 configuration, 26Ohm on-state resistance, and 80MHz bandwidth. The difference is packaging: MC74LVX4052DG is supplied in Tube packaging, while MC74LVXT4052DR2G is supplied in Tape & Reel (TR) format. Select based on your procurement and assembly requirements.

Q: Why do 74HC4052D,653 and 74HCT4052D,118 have different supply voltage ranges?

A: 74HC4052D,653 is a standard CMOS part supporting 2V ~ 10V supply voltage. 74HCT4052D,118 is a TTL-compatible variant optimized for 5V logic systems, with supply range restricted to 4.5V ~ 5.5V. Select 74HCT4052D,118 only for 5V TTL-compatible designs.

Q: Can I substitute CD4052BCMX with MC14052BDG?

A: MC14052BDG has different switch topology (DP4T 2:4 instead of SP4T 4:1) and lower bandwidth (17MHz vs. 40MHz). This is not a direct functional equivalent. Use only if your application can accommodate DP4T switching configuration and lower frequency performance.

Q: What packaging options are available for active substitutes?

A: Active substitutes are available in multiple packaging formats: Tube (DG suffix), Tape & Reel (DR2G suffix), and Cut Tape (CT). All maintain the same 16-SOIC form factor. Select packaging based on your production volume and assembly process requirements.

Q: Are all substitute parts RoHS3 compliant?

A: All active substitute parts listed are RoHS3 compliant and REACH unaffected. The obsolete CD4052BCMX does not have RoHS3 status specified. Verify compliance requirements for your application before final part selection.

Q: What is the temperature range difference between CD4052BCMX and Nexperia parts?

A: CD4052BCMX and onsemi substitutes operate across -55°C ~ 125°C. Nexperia parts (74HC4052D,653 and 74HCT4052D,118) operate across -40°C ~ 125°C. If your application requires operation below -40°C, select onsemi parts.
