74HC4016N,652 Equivalent & Substitute Parts
Part Overview
The 74HC4016N,652 is a 4-circuit SPST-NO analog switch IC manufactured by NXP USA Inc., designed for signal routing and multiplexing applications in the 2V to 10V supply range. This part is classified as Obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The device features 120Ohm on-state resistance, 160MHz bandwidth, and operates across -40°C to 125°C. Substitutes must maintain functional compatibility through matching circuit topology, supply voltage range, and package configuration while accounting for variations in on-state resistance and switching characteristics.

Substitute Part Grouping Explanation
Substitution eligibility for the 74HC4016N,652 is determined by the following mandatory criteria:
Circuit Topology & Configuration: All substitutes must maintain SPST-NO switch circuit type with 4 circuits in 1:1 multiplexer configuration to ensure functional equivalence in signal routing applications.
Package Compatibility: All substitutes must use 14-DIP (0.300", 7.62mm) through-hole package to ensure direct PCB compatibility without layout modifications.
Supply Voltage Range: Substitutes must support the 2V to 10V single supply voltage range. Parts with reduced voltage ranges (e.g., 2V ~ 6V) are functionally compatible only in applications operating within the overlapping voltage window.
On-State Resistance: The 74HC4016N,652 specifies 120Ohm maximum on-state resistance. Substitutes with lower on-state resistance (70Ohm, 30Ohm) provide improved signal integrity and reduced insertion loss, while higher resistance (170Ohm) may impact signal fidelity in bandwidth-sensitive applications.
Regulatory Compliance: All substitutes must maintain ROHS3 compliance and EAR99 export classification to meet procurement and regulatory requirements.
The three qualified substitutes (CD74HC4016E, CD74HC4066E, SN74HC4066N) meet all mandatory criteria while offering variations in switching performance and on-state resistance characteristics.

Engineering Selection Recommendations
CD74HC4016E (Texas Instruments): This substitute maintains identical supply voltage range (2V ~ 10V) and circuit configuration. The 170Ohm on-state resistance represents a 42% increase over the main part, resulting in higher insertion loss and reduced bandwidth (20MHz). This part is suitable for applications where insertion loss is not critical and lower switching speed is acceptable. Extended temperature range (-55°C ~ 125°C) provides broader operational coverage. Product status is Last Time Buy, indicating limited future availability.
CD74HC4066E (Texas Instruments, MFR Recommended): This substitute offers superior performance characteristics with 70Ohm on-state resistance (42% reduction), improved bandwidth (200MHz), and superior crosstalk performance (-72dB @ 1MHz). The 500mOhm channel-to-channel matching ensures excellent uniformity across circuits. Supply voltage range matches the main part (2V ~ 10V). This part is the preferred substitute for applications requiring enhanced signal integrity and bandwidth performance. Extended temperature range (-55°C ~ 125°C) and Last Time Buy status apply.
SN74HC4066N (Texas Instruments): This substitute provides the lowest on-state resistance (30Ohm typical), delivering optimal signal integrity and minimal insertion loss. However, the supply voltage range is restricted to 2V ~ 6V, limiting compatibility to applications operating within this window. Operating temperature range is narrower (-40°C ~ 85°C). Crosstalk performance (-45dB @ 1MHz) is lower than the main part. This part is suitable only for 2V ~ 6V supply applications where low on-state resistance is prioritized. Product status is Last Time Buy.
All three substitutes maintain ROHS3 compliance, EAR99 export classification, and 14-DIP through-hole package compatibility, ensuring regulatory and physical compatibility with the original design.
Frequently Asked Questions (FAQ)
Q: Can CD74HC4016E be used as a direct replacement for 74HC4016N,652?
A: CD74HC4016E is functionally compatible in terms of circuit topology, package, and supply voltage range. However, the 170Ohm on-state resistance is 42% higher than the original 120Ohm specification. This increases insertion loss and reduces bandwidth to 20MHz. Use this substitute only in applications where insertion loss is not performance-critical.
Q: Why is CD74HC4066E recommended as the primary substitute?
A: CD74HC4066E is designated as MFR Recommended and offers superior performance across multiple parameters: 70Ohm on-state resistance (lower insertion loss), 200MHz bandwidth (higher than original), and -72dB crosstalk (better isolation). It maintains the full 2V ~ 10V supply voltage range and provides extended temperature coverage (-55°C ~ 125°C). This part is the optimal choice for signal routing applications requiring high fidelity.
Q: Is SN74HC4066N compatible with all 74HC4016N,652 applications?
A: SN74HC4066N is compatible only with applications operating in the 2V ~ 6V supply voltage range. The 30Ohm on-state resistance provides excellent signal integrity, but the restricted voltage range and narrower operating temperature (-40°C ~ 85°C) limit its applicability. Verify supply voltage requirements before selecting this substitute.
Q: What is the impact of on-state resistance differences on circuit performance?
A: On-state resistance directly affects insertion loss and signal attenuation. Lower resistance (CD74HC4066E at 70Ohm, SN74HC4066N at 30Ohm) reduces signal loss and improves bandwidth performance. Higher resistance (CD74HC4016E at 170Ohm) increases insertion loss and may degrade signal quality in high-frequency or low-level signal applications. Select based on signal integrity requirements.
Q: Are all substitutes available in the same package configuration?
A: Yes. All three substitutes use 14-DIP (0.300", 7.62mm) through-hole package, identical to the main part. Direct PCB compatibility is maintained without layout modifications.
Q: What is the significance of "Last Time Buy" product status?
A: Last Time Buy indicates that the manufacturer will discontinue production after a specified date. Substitutes with this status have limited future availability. Plan procurement accordingly and consider long-term supply chain implications when selecting alternatives.
Q: Do all substitutes meet the same regulatory requirements as the original part?
A: Yes. All three substitutes maintain ROHS3 compliance and EAR99 export classification, matching the regulatory profile of the 74HC4016N,652. Moisture Sensitivity Level (MSL) is Not Applicable for all Texas Instruments substitutes, compared to MSL 1 (Unlimited) for the original NXP part.
