CD4067BME4 Equivalent & Substitute Parts

Part Overview

The CD4067BME4 is a 16:1 analog multiplexer/demultiplexer interface IC manufactured by Texas Instruments in 24-SOIC surface mount packaging. This device functions as a single-channel switch with 240Ω on-state resistance, operating across a 3V to 18V supply range. The CD4067BME4 is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. Substitute parts must maintain functional equivalence in multiplexer configuration, switching characteristics, and package compatibility while meeting current availability and compliance requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the CD4067BME4 is determined by the following mandatory parameters:

Core Functional Requirements:

Multiplexer/Demultiplexer configuration: 16:1
Number of circuits: 1
Package type: 24-SOIC surface mount
Supply voltage range: 3V ~ 18V minimum
Operating temperature range: -55°C ~ 125°C minimum

Electrical Performance Criteria:

On-state resistance tolerance: Maximum 280Ω (allows minor variance from 240Ω specification)
Leakage current: 100nA maximum
Channel capacitance compatibility within specified ranges

Substitute parts are grouped into two categories based on electrical performance alignment:

Category A - Direct Electrical Match (240Ω On-State Resistance): CD4067BM96, CD4067BM — Texas Instruments parts maintaining identical on-state resistance and channel matching specifications.

Category B - Compatible Alternative (280Ω On-State Resistance): MC14067BDWR2G, MC14067BDWG, NLV14067BDWR2G — onsemi parts with slightly elevated on-state resistance but equivalent functional performance within the 16:1 multiplexer architecture.

Category C - Limited Specification Data: HEF4067BT,653 — NXP Semiconductors part with confirmed 16:1 multiplexer configuration and 24-SOIC packaging; full electrical specifications not provided in source data.

Engineering Selection Recommendations

Primary Recommendation: CD4067BM96

CD4067BM96 is the preferred substitute for CD4067BME4. This Texas Instruments part maintains identical electrical specifications including 240Ω on-state resistance, 5Ω channel matching, and 14MHz bandwidth. Product status is Active with high inventory availability (33,500 pcs), ensuring supply continuity. Packaging is Cut Tape (CT) & Digi-Reel®, suitable for automated assembly. MSL rating of 1 (Unlimited) matches the original part. ROHS3 compliance and REACH unaffected status maintain regulatory alignment.

Secondary Recommendation: CD4067BM

CD4067BM provides identical electrical performance to CD4067BME4 with the same 240Ω on-state resistance and 14MHz bandwidth. Product status is Last Time Buy, indicating limited future availability. Tube packaging is suitable for manual assembly operations. This part is appropriate for designs where supply continuity beyond current inventory is not critical.

Alternative Recommendation: MC14067BDWR2G

MC14067BDWR2G (onsemi) is functionally compatible with elevated on-state resistance of 280Ω and 10Ω channel matching. This part is Active with substantial inventory (39,200 pcs). The -3dB bandwidth of 15MHz exceeds the original specification. MSL rating of 3 (168 Hours) requires controlled storage conditions. This substitute is suitable for applications where the 40Ω resistance increase and enhanced bandwidth do not create circuit performance constraints.

Automotive-Grade Alternative: NLV14067BDWR2G

NLV14067BDWR2G is an onsemi automotive-qualified part (AEC-Q100) with 280Ω on-state resistance. MSL rating of 1 (Unlimited) provides handling advantages. This part is appropriate for automotive applications requiring AEC-Q100 qualification where the resistance specification variance is acceptable.

Frequently Asked Questions (FAQ)

Q: Can CD4067BM96 directly replace CD4067BME4 without circuit modification?

A: Yes. CD4067BM96 maintains identical electrical specifications across all critical parameters: 240Ω on-state resistance, 5Ω channel matching, 14MHz bandwidth, and 24-SOIC packaging. No circuit modifications are required.

Q: What is the impact of using MC14067BDWR2G with its 280Ω on-state resistance instead of 240Ω?

A: The 40Ω increase in on-state resistance affects signal attenuation and impedance matching in analog signal paths. Applications with high-impedance loads or precision analog switching may experience measurable performance changes. Circuit simulation or bench testing is necessary to confirm suitability for specific applications.

Q: Why does NLV14067BDWR2G have MSL 1 while MC14067BDWR2G has MSL 3?

A: MSL rating reflects moisture sensitivity during storage and handling. NLV14067BDWR2G's MSL 1 (Unlimited) indicates lower moisture absorption risk, providing handling flexibility. MC14067BDWR2G's MSL 3 (168 Hours) requires controlled storage and faster assembly after package opening.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the regulatory profile of CD4067BME4.

Q: What packaging options are available among substitute parts?

A: CD4067BM96 is supplied in Cut Tape (CT) & Digi-Reel® format for automated assembly. CD4067BM is supplied in Tube format for manual assembly. MC14067BDWR2G is supplied in Cut Tape (CT) & Digi-Reel® format. MC14067BDWG is supplied in Tube format. NLV14067BDWR2G packaging is not specified in available data. HEF4067BT,653 is supplied in Bulk format.

Q: Is HEF4067BT,653 a suitable substitute if complete specifications are unavailable?

A: HEF4067BT,653 is functionally compatible as a 16:1 multiplexer in 24-SOIC packaging with Active product status. However, complete electrical specifications must be obtained from the NXP datasheet before design integration to confirm parameter alignment with application requirements.
