CD4052BM Equivalent & Substitute Parts

Part Overview

The CD4052BM is a dual 4:1 analog multiplexer/demultiplexer IC manufactured by Texas Instruments, housed in a 16-SOIC surface mount package. This interface component features SP4T switch configuration with 240Ohm on-state resistance and operates across a wide supply voltage range of 3V to 20V (single supply) or ±2.5V to 9V (dual supply). The CD4052BM is currently designated as Last Time Buy, indicating production discontinuation. Identifying equivalent and substitute parts is necessary to ensure design continuity and maintain component availability for new production runs and field replacements.

Substitute Part Grouping Explanation

Substitution eligibility for the CD4052BM is determined by the following critical parameters:

Primary Substitution Criteria:

Switch circuit configuration (SP4T or equivalent dual-circuit topology)
Multiplexer/demultiplexer circuit type (4:1 configuration)
Number of circuits (2 independent circuits)
Package type (16-SOIC surface mount)
On-state resistance compatibility (240Ohm nominal, with tolerance consideration)
Supply voltage range overlap (minimum 3V to 20V single supply capability)
Operating temperature range (minimum -55°C to 125°C)

Secondary Compatibility Factors:

Channel-to-channel matching (ΔRon tolerance)
Leakage current specifications
Bandwidth performance
RoHS and MSL compliance

Substitute parts are grouped into two categories:

Category A - Direct Functional Equivalents (Identical Specifications): Parts maintaining identical switch configuration, circuit count, on-state resistance, and supply voltage ranges. These parts provide drop-in replacement capability with no design modifications required.

Category B - Compatible Alternatives (Parameter Variance): Parts with SP4T configuration and 4:1 multiplexing but differing on-state resistance, bandwidth, or supply voltage specifications. These parts require design verification to confirm compatibility within the target application's electrical constraints.

Engineering Selection Recommendations

Recommended Primary Substitute: CD4052BM96

CD4052BM96 is the direct equivalent manufactured by Texas Instruments with identical electrical specifications and 16-SOIC packaging. This part maintains 240Ohm on-state resistance, 3V to 20V single supply operation, and -55°C to 125°C temperature range. CD4052BM96 is currently in Active product status with high inventory availability (95,200 units), ensuring supply chain continuity. ROHS3 compliance and MSL Level 1 rating match the original specification. This part requires no design modifications and provides the highest compatibility assurance.

Secondary Substitutes for Extended Temperature Range Applications:

HEF4052BT,653 (Nexperia) maintains SP4T configuration with 155Ohm on-state resistance and operates across 3V to 15V single supply. Operating temperature range is -40°C to 125°C, which is narrower than the original but suitable for most industrial applications. This part is Active with 13,331 units in stock.

Substitutes for Low-Voltage Applications:

74LV4052D,118 (Nexperia) operates from 1V to 6V single supply with reduced 85Ohm on-state resistance and superior 200MHz bandwidth. This part is suitable for battery-powered and low-voltage digital systems. Operating temperature is -40°C to 125°C. Use this part only when supply voltage constraints require operation below 3V.

Substitutes for High-Speed Applications:

74HC4052D,653 (Nexperia) provides 180MHz bandwidth with 150Ohm on-state resistance and operates from 2V to 10V single supply. This part is suitable for high-frequency signal routing applications. Operating temperature is -40°C to 125°C. Note that the minimum supply voltage is 2V, which is below the CD4052BM specification.

Not Recommended for Direct Substitution:

MC14052BDR2G (onsemi) uses DP4T switch configuration instead of SP4T, representing a different circuit topology. Although it maintains 2-circuit count and 16-SOIC packaging, the DP4T configuration is not functionally equivalent to the SP4T topology of the CD4052BM.

MAX4559 series (Analog Devices/Maxim) parts operate with narrower temperature range (0°C to 70°C or -40°C to 85°C) compared to the CD4052BM specification of -55°C to 125°C. These parts are suitable only for applications not requiring the full extended temperature range.

Frequently Asked Questions (FAQ)

Q: Can CD4052BM96 be used as a direct replacement for CD4052BM?

A: Yes. CD4052BM96 is manufactured by Texas Instruments with identical electrical specifications, including 240Ohm on-state resistance, SP4T switch configuration, 4:1 multiplexing, dual-circuit topology, and -55°C to 125°C operating temperature. Both parts use 16-SOIC packaging and maintain ROHS3 compliance. No design modifications are required.

Q: What is the difference between SP4T and DP4T switch configurations?

A: SP4T (Single Pole 4-Throw) routes one input signal to one of four output channels. DP4T (Dual Pole 4-Throw) routes two independent input signals, each to one of four output channels. These are different circuit topologies and are not functionally interchangeable. The CD4052BM uses SP4T configuration with two independent SP4T switches.

Q: Can 74HC4052D,653 replace CD4052BM in all applications?

A: 74HC4052D,653 maintains SP4T configuration and 4:1 multiplexing but differs in three critical parameters: on-state resistance (150Ohm vs. 240Ohm), supply voltage range (2V to 10V vs. 3V to 20V), and operating temperature (−40°C to 125°C vs. −55°C to 125°C). Substitution is valid only if the application operates within 2V to 10V supply range and does not require operation below −40°C. The lower on-state resistance may improve signal integrity in some applications.

Q: Why does MAX4559CSE+T have a narrower operating temperature range?

A: MAX4559CSE+T is specified for 0°C to 70°C operation, which is narrower than the CD4052BM range of −55°C to 125°C. This reflects the design intent and qualification testing performed by Analog Devices/Maxim Integrated. Use this part only in applications where the operating environment remains within 0°C to 70°C.

Q: Are all substitute parts available in 16-SOIC packaging?

A: Yes. All substitute parts listed are housed in 16-SOIC (0.154", 3.90mm Width) surface mount packages, ensuring PCB footprint compatibility with the original CD4052BM design.

Q: What does "Last Time Buy" status mean for CD4052BM?

A: Last Time Buy indicates that Texas Instruments has discontinued production of the CD4052BM. Existing inventory may be available from authorized distributors, but no new manufacturing runs are planned. CD4052BM96 is the recommended active replacement from the same manufacturer.

Q: Can 74LV4052D,118 operate at the CD4052BM supply voltage of 20V?

A: No. 74LV4052D,118 is specified for 1V to 6V single supply operation. It cannot operate at 20V and will be damaged if exposed to this voltage. This part is suitable only for low-voltage applications.

Q: What is the significance of MSL Level 1 rating?

A: MSL (Moisture Sensitivity Level) 1 indicates unlimited shelf life without moisture control requirements. Both the CD4052BM and all substitute parts carry MSL Level 1 rating, meaning they do not require special moisture-controlled storage or handling procedures.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed carry ROHS3 compliance certification, matching the environmental compliance status of the original CD4052BM.
