Substitute Part Grouping Explanation

Substitution eligibility for the 74HC4067DB,112 is determined by the following critical parameters:

Functional Requirements:

Multiplexer/Demultiplexer configuration must be 16:1
Single circuit configuration (1 circuit)
Base product number 74HC4067 family

Electrical Compatibility:

On-state resistance and channel matching must support the application's signal integrity requirements
Supply voltage range must encompass the design operating point
Switch timing and bandwidth must meet signal routing performance specifications
Leakage current must remain within acceptable limits for the application

Physical & Environmental:

Surface mount technology with compatible package footprint

Engineering Selection Recommendations

74HC4067PW,118 (Nexperia USA Inc.) - Preferred Direct Substitute

This part maintains identical electrical specifications to the 74HC4067DB,112 across all critical parameters: 120Ohm on-state resistance, 6Ohm channel matching, 2V–10V supply range, 45ns switching time, and 100MHz bandwidth. The primary difference is package geometry: 24-TSSOP (0.173" width) versus 24-SSOP (0.209" width). Both packages are surface-mount with identical pin counts and functional compatibility. The 74HC4067PW,118 carries Active product status with full RoHS3 compliance and MSL 1 rating, ensuring long-term availability and manufacturing support.

CD74HC4067SM96 (Texas Instruments) - Functional Substitute with Performance Trade-offs

This Texas Instruments alternative provides 16:1 multiplexer functionality in the same 24-SSOP package footprint as the original part. However, electrical performance differs in four areas: on-state resistance increases to 160Ohm (versus 120Ohm), channel matching widens to 8.5Ohm (versus 6Ohm), supply voltage range narrows to 2V–6V (versus 2V–10V), and leakage current rises to 800nA (versus 100nA). Switching time extends to 51ns/49ns, and bandwidth reduces to 89MHz. The CD74HC4067SM96 supports an extended operating temperature range (-55°C to 125°C) and maintains Active status with full compliance certifications. This part is suitable only for applications where the relaxed electrical specifications and narrower supply range do not compromise system performance.

Frequently Asked Questions (FAQ)

Q: Can the 74HC4067PW,118 replace the 74HC4067DB,112 directly on the PCB?

A: Electrical substitution is complete. Package substitution requires PCB layout verification. The 74HC4067PW,118 uses 24-TSSOP packaging (0.173" width) while the original uses 24-SSOP (0.209" width). Both are 24-pin surface-mount packages with identical pin assignments. Footprint compatibility depends on whether the PCB was designed with tolerance for the narrower TSSOP body width. If the original PCB footprint was designed specifically for SSOP dimensions, the TSSOP package may not seat properly. Consult PCB layout documentation and footprint specifications before implementation.

Q: What are the key differences between the Nexperia and Texas Instruments options?

A: The 74HC4067PW,118 (Nexperia) provides electrical equivalence with identical on-state resistance, matching, supply range, and switching performance. The CD74HC4067SM96 (Texas Instruments) trades electrical performance for extended temperature range. The TI part exhibits higher on-state resistance (160Ohm vs. 120Ohm), wider channel matching tolerance (8.5Ohm vs. 6Ohm), narrower supply voltage window (2V–6V vs. 2V–10V), and significantly higher leakage current (800nA vs. 100nA). Select the Nexperia part for applications requiring the original electrical specifications; select the TI part only if extended low-temperature operation (-55°C minimum) is essential and the relaxed electrical parameters are acceptable.

Q: Are both substitute parts available in the same packaging options?

A: No. The 74HC4067PW,118 is supplied in Cut Tape (CT) and Digi-Reel® packaging. The CD74HC4067SM96 is also supplied in Cut Tape (CT) and Digi-Reel® packaging. Both parts maintain MSL 1 (Unlimited) moisture sensitivity ratings, eliminating special storage or handling requirements. Verify packaging availability with your component supplier for production volume requirements.

Q: Does the narrower supply voltage range of the CD74HC4067SM96 affect system compatibility?

A: Yes, if your design operates above 6V. The CD74HC4067SM96 maximum supply voltage is 6V, while the original 74HC4067DB,112 and the 74HC4067PW,118 both support up to 10V. If your application requires supply voltages between 6V and 10V, the Texas Instruments part is not suitable. Verify your system's actual operating voltage before selecting this substitute.

Q: What is the significance of the higher leakage current in the CD74HC4067SM96?

A: The CD74HC4067SM96 exhibits 800nA maximum leakage current compared to 100nA in the original part—an 8-fold increase. In applications with high-impedance signal paths, precision analog switching, or low-power standby requirements, this elevated leakage may introduce unacceptable signal degradation or power consumption. Evaluate leakage impact on your specific application before selecting this part.
