CD4067BM Equivalent & Substitute Parts

Part Overview

The CD4067BM is a 16:1 analog multiplexer/demultiplexer interface circuit manufactured by Texas Instruments in 24-SOIC surface mount packaging. This single-circuit switch device features 240Ω maximum on-state resistance and operates across a 3V to 18V supply voltage range, making it suitable for signal routing and switching applications in industrial and commercial electronics.

The CD4067BM carries a Last Time Buy product status, indicating production discontinuation. Identifying functionally equivalent substitute parts is necessary to ensure design continuity and maintain supply chain reliability for new production runs and long-term support.

Engineering Selection Recommendations

Tier 1 - Direct Replacement (Identical Specifications):

CD4067BM96 is the primary substitute. Manufactured by Texas Instruments with identical electrical specifications (240Ω on-state resistance, 5Ω channel matching, 14MHz bandwidth), this part maintains full parameter compatibility. Product status is Active with unlimited MSL rating, ensuring long-term availability and simplified handling requirements.

Tier 2 - Functional Equivalent (Acceptable Parameter Variance):

MC14067BDWG and MC14067BDWR2G (onsemi) provide functional equivalence with acceptable parameter tolerance. On-state resistance increases to 280Ω maximum with 10Ω channel matching, and bandwidth improves to 15MHz. Both maintain 3V to 18V supply compatibility and identical package geometry. MSL rating of 3 (168 Hours) requires controlled storage conditions. MC14067BDWR2G offers higher inventory availability in Cut Tape & Digi-Reel packaging.

Tier 3 - Specialized Application:

NLV14067BDWR2G (onsemi) qualifies as an automotive-grade substitute with AEC-Q100 qualification. Electrical parameters match the MC14067 series (280Ω on-state resistance, 10Ω matching). MSL rating returns to 1 (Unlimited), simplifying logistics. This part is appropriate for automotive and mission-critical applications requiring automotive qualification.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance and REACH Unaffected status, matching the original CD4067BM regulatory profile. Selection should prioritize Active product status parts (CD4067BM96, MC14067BDWG, MC14067BDWR2G, NLV14067BDWR2G) to ensure sustained supply chain support beyond the CD4067BM Last Time Buy window.

Frequently Asked Questions (FAQ)

Q: Can I use MC14067BDWG as a direct replacement for CD4067BM?

A: Yes, with design verification. The MC14067BDWG maintains the 16:1 multiplexer configuration, 24-SOIC package, and 3V to 18V supply range. On-state resistance increases from 240Ω to 280Ω maximum, which is acceptable for most signal routing applications. Verify that your circuit design tolerates the higher on-state resistance and 10Ω channel matching variance before production implementation.

Q: What is the difference between CD4067BM96 and CD4067BM?

A: CD4067BM96 is the Active production variant of the CD4067BM. Electrical specifications are identical (240Ω on-state resistance, 5Ω matching, 14MHz bandwidth). The primary difference is packaging format: CD4067BM ships in Tube packaging, while CD4067BM96 is available in Cut Tape & Digi-Reel format. Both are Texas Instruments products with unlimited MSL rating.

Q: Why do some substitute parts have higher on-state resistance?

A: The onsemi MC14067 series (MC14067BDWG, MC14067BDWR2G, NLV14067BDWR2G) specify 280Ω maximum on-state resistance compared to the Texas Instruments 240Ω specification. This represents acceptable manufacturing tolerance variance within the 16:1 multiplexer product category. Applications sensitive to on-state resistance should prioritize Texas Instruments parts (CD4067BM or CD4067BM96) or conduct circuit simulation to confirm compatibility.

Q: Is NLV14067BDWR2G suitable for non-automotive applications?

A: Yes. NLV14067BDWR2G carries automotive AEC-Q100 qualification, but this does not restrict use in standard industrial or commercial applications. The automotive qualification indicates enhanced reliability screening and is not a limitation for general-purpose signal routing. This part offers the advantage of unlimited MSL rating (1) combined with Active product status.

Q: What packaging options are available for substitutes?

A: CD4067BM96 is available in Cut Tape & Digi-Reel packaging. MC14067BDWG ships in Tube format. MC14067BDWR2G is available in Cut Tape & Digi-Reel. NLV14067BDWR2G packaging format is not specified in available data. All parts use identical 24-SOIC (0.295", 7.50mm Width) case geometry, ensuring PCB footprint compatibility.

Q: How does MSL rating affect part selection?

A: CD4067BM, CD4067BM96, and NLV14067BDWR2G carry MSL 1 (Unlimited), allowing indefinite shelf storage without moisture bake-out procedures. MC14067BDWG and MC14067BDWR2G carry MSL 3 (168 Hours), requiring moisture bake-out if storage exceeds 168 hours at specified humidity conditions. For high-volume production with extended lead times, prioritize MSL 1 rated parts to simplify supply chain logistics.
