Engineering Selection Recommendations

Direct Electrical Equivalents (Tier 1):

CD74HC4067M96 is the primary substitute. This Texas Instruments part maintains identical electrical specifications including 160Ohm on-state resistance, 89MHz bandwidth, and 2V to 6V supply range. Both parts share MSL 1 rating and ROHS3 compliance. The distinction is packaging format: CD74HC4067M96 is supplied in Cut Tape and Digi-Reel format versus tube packaging for the original part. This substitute is suitable for direct replacement in all applications where the CD74HC4067M was specified.

Functional Equivalents with Parameter Deviations (Tier 2):

MC14067BDWG and MC14067BDWR2G (onsemi) provide 16:1 multiplexer functionality in 24-SOIC packaging with active product status. These parts operate across a wider supply range (3V to 18V) but exhibit higher on-state resistance (280Ohm maximum) and reduced bandwidth (15MHz). The MSL 3 rating requires controlled moisture exposure during storage and handling. These substitutes are applicable only when the higher on-state resistance and lower bandwidth do not violate circuit performance requirements.

Limited Data Substitute:

HEF4067BT,653 (NXP Semiconductors) is listed as a functional equivalent with 16:1 multiplexer configuration and active status. Insufficient electrical parameter data is provided for detailed compatibility assessment. This part should be evaluated against specific application requirements before selection.

Frequently Asked Questions (FAQ)

Q: Can CD74HC4067M96 replace CD74HC4067M directly?

A: Yes. CD74HC4067M96 is electrically identical to CD74HC4067M with matching on-state resistance (160Ohm), bandwidth (89MHz), supply voltage range (2V to 6V), and operating temperature range (-55°C to 125°C). The only difference is packaging format (Cut Tape/Digi-Reel versus Tube). Both maintain MSL 1 rating and ROHS3 compliance.

Q: What are the limitations of MC14067BDWG and MC14067BDWR2G substitutes?

A: These onsemi parts increase on-state resistance from 160Ohm to 280Ohm and reduce bandwidth from 89MHz to 15MHz. The wider supply voltage range (3V to 18V) may be advantageous in some applications but does not offset the performance reduction in high-speed or low-impedance switching circuits. MSL 3 rating requires moisture control during storage.

Q: Are the onsemi MC14067 variants suitable for high-frequency applications?

A: No. The 15MHz bandwidth of MC14067BDWG and MC14067BDWR2G is significantly lower than the CD74HC4067M specification of 89MHz. Applications requiring bandwidth above 15MHz must use CD74HC4067M96 or equivalent high-speed variants.

Q: What is the difference between CD74HC4067M and CD74HC4067M96 packaging?

A: CD74HC4067M is supplied in Tube packaging. CD74HC4067M96 is supplied in Cut Tape and Digi-Reel format. Both are 24-SOIC surface mount packages with identical physical dimensions and electrical specifications. Selection depends on assembly process requirements and component handling procedures.

Q: Can HEF4067BT,653 be used as a substitute?

A: HEF4067BT,653 provides 16:1 multiplexer functionality with active product status. However, complete electrical parameter specifications are not provided in the available data. Verification against application-specific requirements is necessary before implementation.

Q: What is the impact of MSL rating differences?

A: CD74HC4067M and CD74HC4067M96 carry MSL 1 rating (unlimited moisture exposure tolerance). MC14067BDWG and MC14067BDWR2G carry MSL 3 rating (168-hour maximum exposure at specified humidity). MSL 3 parts require controlled storage conditions and accelerated baking procedures if moisture absorption limits are exceeded during handling.
