CD74HC4016PW Equivalent & Substitute Parts

Part Overview

The CD74HC4016PW is a 4-circuit SPST-NO analog switch IC manufactured by Texas Instruments in 14-TSSOP surface mount packaging. This device functions as a single-pole single-throw normally-open switch array with 170Ω maximum on-state resistance per channel. The part is classified as Last Time Buy, indicating end-of-life status. Alternative equivalent parts are necessary for new designs and ongoing production requirements where active product status and improved electrical performance characteristics are preferred.

Substitute Part Grouping Explanation

Substitution eligibility for the CD74HC4016PW is determined by the following mandatory criteria:

Core Compatibility Requirements:

Switch circuit type: SPST - NO (normally-open configuration)
Number of circuits: 4
Package type: 14-TSSOP surface mount
Supply voltage range: Must encompass or be compatible with 2V ~ 10V
Mounting type: Surface mount

Performance Considerations: Substitute parts may exhibit improved electrical characteristics including lower on-state resistance, better channel matching, higher bandwidth, and lower leakage current. These improvements do not prevent substitution; they represent performance enhancements. Parts with different supply voltage ranges, different switch circuit types (NC or NO/NC), or different package configurations are classified as alternative solutions rather than direct substitutes.

Engineering Selection Recommendations

Direct Substitutes (Active Product Status):

CD74HC4066PWR and 74HC4066PW-Q100,11 are primary substitutes for the CD74HC4016PW. Both maintain SPST-NO switch configuration, 4-circuit architecture, and 14-TSSOP packaging. CD74HC4066PWR offers improved on-state resistance (70Ω) and is available in active product status from Texas Instruments. The 74HC4066PW-Q100,11 variant from Nexperia includes AEC-Q100 automotive qualification and is suitable for applications requiring automotive-grade components.

Performance-Enhanced Alternatives:

MAX4737EUD+T and MAX4747EUD+T represent performance-enhanced alternatives with significantly lower on-state resistance (4.5Ω and 25Ω respectively) and superior bandwidth characteristics (300MHz and 250MHz). These parts maintain SPST-NO configuration and 14-TSSOP packaging but operate within a narrower supply voltage range (1.8V ~ 5.5V for MAX4737, 2V ~ 11V for MAX4747). Selection depends on application voltage requirements and performance specifications.

Compliance Considerations:

All listed substitutes maintain ROHS3 compliance and MSL Level 1 moisture sensitivity rating. The 74HC4066PW-Q100,11 includes AEC-Q100 qualification for automotive applications. Operating temperature ranges vary: CD74HC4016PW and CD74HC4066PWR support -55°C ~ 125°C, while MAX4737EUD+T and MAX4747EUD+T are limited to -40°C ~ 85°C.

Frequently Asked Questions (FAQ)

Q: Can MAX4738EUD+T and MAX4749EUD+T be used as substitutes for CD74HC4016PW?

A: MAX4738EUD+T and MAX4749EUD+T are not direct substitutes. MAX4738EUD+T implements SPST-NC (normally-closed) switch configuration, which is functionally different from the SPST-NO requirement. MAX4749EUD+T provides SPST-NO/NC mixed configuration. Both are alternative solutions for applications requiring different switch logic.

Q: What is the primary reason to substitute CD74HC4016PW?

A: CD74HC4016PW is classified as Last Time Buy, indicating discontinued production. Active product alternatives ensure long-term supply availability and support for new designs and production continuity.

Q: Are there supply voltage compatibility issues when substituting with MAX4737EUD+T?

A: MAX4737EUD+T operates within 1.8V ~ 5.5V supply range, which does not fully encompass the CD74HC4016PW range of 2V ~ 10V. Applications requiring supply voltages above 5.5V are not compatible with MAX4737EUD+T. Verify application voltage requirements before selection.

Q: What packaging options are available for substitute parts?

A: All listed substitutes are available in 14-TSSOP surface mount packaging, matching the CD74HC4016PW form factor. Packaging variants include Tube, Tape & Reel (TR), and Cut Tape (CT) & Digi-Reel options depending on the specific part number and manufacturer.

Q: How do on-state resistance differences affect circuit performance?

A: Lower on-state resistance reduces signal attenuation and power dissipation in switching applications. CD74HC4066PWR (70Ω) and 74HC4066PW,118 (95Ω) provide moderate improvements over CD74HC4016PW (170Ω). MAX4737EUD+T (4.5Ω) and MAX4747EUD+T (25Ω) deliver substantial resistance reduction for applications requiring minimal signal loss.

Q: Is automotive qualification required for all applications?

A: Automotive qualification is application-specific. The 74HC4066PW-Q100,11 includes AEC-Q100 qualification for automotive-grade requirements. Standard industrial and commercial applications may use non-qualified alternatives such as CD74HC4066PWR or MAX4747EUD+T.
