Substitute Part Grouping Explanation

Substitution for the 74HC4067PW,112 is determined by the following critical parameters:

Multiplexer Configuration: 16:1 topology (mandatory match)
Package Type: 24-TSSOP surface mount form factor (mandatory match)
On-State Resistance: Maximum 120Ohm specification
Supply Voltage Range: 2V ~ 10V single supply operation
Leakage Current: 100nA maximum specification
Operating Temperature Range: -40°C ~ 125°C minimum coverage
RoHS3 Compliance: Environmental and regulatory requirement

The CD4067BPW and CD4067BPWR variants from Texas Instruments share the identical 16:1 multiplexer configuration and 24-TSSOP package. However, these substitutes feature a higher on-state resistance of 240Ohm and an expanded supply voltage range of 3V ~ 18V, which affects their suitability depending on application requirements.

Engineering Selection Recommendations

CD4067BPWR is the primary substitute option. This part maintains Active product status from Texas Instruments, ensuring long-term availability and supply chain stability. It carries ROHS3 compliance and MSL Level 1 rating identical to the original component. The 24-TSSOP package provides direct mechanical compatibility without PCB redesign.

CD4067BPW serves as a secondary alternative with Last Time Buy status, indicating limited future availability. This variant shares all electrical and mechanical specifications with CD4067BPWR but carries higher obsolescence risk.

Critical Design Considerations: Both CD4067 variants operate with a 240Ohm maximum on-state resistance, double that of the 74HC4067PW,112. Applications requiring the lower 120Ohm resistance specification must evaluate signal integrity and impedance matching implications. The CD4067 series supports a wider supply voltage range (3V ~ 18V) but operates at reduced bandwidth (14MHz versus 100MHz), which may impact high-frequency signal routing applications.

Frequently Asked Questions (FAQ)

Q: Can CD4067BPWR directly replace 74HC4067PW,112 without circuit modification?

A: Mechanical and electrical pin compatibility exists due to identical 16:1 multiplexer topology and 24-TSSOP packaging. However, the doubled on-state resistance (240Ohm vs. 120Ohm) affects signal attenuation and impedance characteristics. Circuit simulation or bench testing is necessary to confirm performance within application-specific signal integrity requirements.

Q: What is the primary difference between CD4067BPW and CD4067BPWR?

A: Both variants share identical electrical specifications and 24-TSSOP packaging. The distinction lies in packaging format (Tube for CD4067BPW versus Tape & Reel for CD4067BPWR) and product status (Last Time Buy versus Active). CD4067BPWR is recommended for new designs due to Active status and superior long-term availability.

Q: Does the reduced bandwidth of CD4067 (14MHz vs. 100MHz) affect all applications?

A: Bandwidth impact depends on signal frequency content. Applications operating below 14MHz experience minimal degradation. High-frequency analog signal routing or fast digital switching applications may require performance re-evaluation. The 45ns switch time specification of the original part is not provided for CD4067 variants, necessitating detailed datasheet review for timing-critical designs.

Q: Are supply voltage ranges compatible between 74HC4067PW,112 and CD4067 variants?

A: The 74HC4067PW,112 operates within 2V ~ 10V, while CD4067 variants operate within 3V ~ 18V. Designs using supply voltages between 3V and 10V are compatible with both parts. Designs requiring 2V operation cannot use CD4067 substitutes. Designs utilizing supply voltages above 10V require CD4067 variants.

Q: Are both substitute parts RoHS3 compliant?

A: Yes. CD4067BPW and CD4067BPWR both carry ROHS3 Compliant certification with MSL Level 1 rating, matching the environmental compliance profile of the original 74HC4067PW,112.
