CD4052BCN Equivalent & Substitute Parts

Part Overview

The CD4052BCN is a 2-circuit SP4T analog switch IC manufactured by onsemi, designed for signal routing and multiplexing applications. It features a 4:1 multiplexer/demultiplexer configuration with 240Ohm on-state resistance and operates across a wide supply voltage range of 5V to 15V (single supply) or ±2.5V to ±7.5V (dual supply). The device is rated for -55°C to 125°C operating temperature and is housed in a 16-DIP package.

The CD4052BCN is classified as obsolete. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support long-term product availability for applications requiring this functional specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD4052BCN is determined by the following critical parameters:

Functional Requirements:

• Switch circuit configuration: SP4T
• Multiplexer/demultiplexer circuit: 4:1
• Number of circuits: 2
• Package type: 16-DIP through-hole

Electrical Compatibility:

• On-state resistance and channel matching must support the application's signal integrity requirements
• Supply voltage range must encompass the system's operating voltage
• Operating temperature range must cover the application's thermal environment
• Bandwidth and switching speed must meet signal fidelity requirements

Substitute parts are grouped into two categories:

1. Direct Functional Equivalents (CD4052BE): Maintains identical switch circuit configuration, multiplexer ratio, and circuit count with compatible electrical specifications and active product status.

2. Enhanced Performance Alternatives (CD74HC4052E, CD74HCT4052E): Provide improved bandwidth and reduced on-state resistance while maintaining the same functional architecture and package form factor, though with different supply voltage operating ranges.

Parameter Comparison

Engineering Selection Recommendations

CD4052BE (Texas Instruments): This part is the primary substitute for the CD4052BCN. It maintains identical on-state resistance (240Ohm) and channel matching (5Ohm), ensuring signal integrity equivalent to the original design. The CD4052BE offers an expanded single-supply voltage range (3V to 20V) compared to the CD4052BCN (5V to 15V), providing greater design flexibility. The device is currently in active production status, ensuring long-term availability and supply chain stability. RoHS3 compliance supports modern manufacturing and environmental standards.

CD74HC4052E (Texas Instruments): This part provides enhanced performance characteristics with reduced on-state resistance (130Ohm) and significantly improved bandwidth (185MHz versus 40MHz). However, the single-supply voltage range is restricted to 2V to 6V, which may not be compatible with systems designed for the CD4052BCN's 5V to 15V range. The CD74HC4052E is designated as Last Time Buy, indicating limited future availability. This part is suitable only for applications where the narrower voltage range is acceptable and the improved bandwidth provides measurable system benefit.

CD74HCT4052E (Harris Corporation): This part shares the enhanced bandwidth (185MHz) and reduced on-state resistance (130Ohm) of the CD74HC4052E but is restricted to a narrow single-supply voltage range of 4.5V to 5.5V. The device is classified as obsolete, making it unsuitable for new designs or long-term supply commitments. RoHS non-compliance further limits its applicability in modern manufacturing environments.

Frequently Asked Questions (FAQ)

Q: Can the CD4052BE directly replace the CD4052BCN in existing designs?

A: Yes. The CD4052BE maintains identical functional specifications including SP4T switch configuration, 4:1 multiplexer ratio, 2-circuit count, 240Ohm on-state resistance, and 16-DIP package. The expanded supply voltage range (3V to 20V) provides additional design margin. Active product status ensures continued availability.

Q: What are the key differences between CD4052BE and CD74HC4052E?

A: The primary differences are on-state resistance (240Ohm versus 130Ohm), bandwidth (25MHz versus 185MHz), and supply voltage range (3V-20V versus 2V-6V). The CD74HC4052E offers superior high-frequency performance but operates only at lower supply voltages. Selection depends on whether the application requires the improved bandwidth and can operate within the restricted voltage range.

Q: Are all substitute parts available in the same 16-DIP package?

A: Yes. All listed substitute parts (CD4052BE, CD74HC4052E, CD74HCT4052E) are packaged in 16-DIP (0.300", 7.62mm) through-hole configuration, ensuring mechanical compatibility with existing PCB designs.

Q: Why is the CD4052BCN classified as obsolete?

A: The CD4052BCN is an older generation CMOS analog switch. Modern alternatives such as the CD4052BE offer improved specifications, better compliance certifications, and active manufacturing status, making them preferred for new designs and ongoing production.

Q: What is the significance of RoHS compliance in selecting a substitute?

A: RoHS3 compliance (CD4052BE, CD74HC4052E) indicates the part meets current environmental and manufacturing standards required by many industries and regions. The CD74HCT4052E's RoHS non-compliance may restrict its use in applications subject to environmental regulations or customer requirements.

Q: Can the CD74HCT4052E be used as a substitute?

A: The CD74HCT4052E is not recommended. Although it shares the enhanced bandwidth of the CD74HC4052E, its narrow supply voltage range (4.5V-5.5V) limits compatibility, and its obsolete status creates supply chain risk. The CD4052BE is the preferred alternative.
