MM74HC4316N Equivalent & Substitute Parts

Part Overview

The MM74HC4316N is a 4-circuit IC switch with SPST-NO (Single Pole Single Throw - Normally Open) configuration, manufactured by onsemi. This component functions as a high-speed analog switch suitable for signal routing and multiplexing applications in the 2V to 12V single supply or ±2V to ±6V dual supply range. The part is classified as obsolete, making identification of functionally equivalent alternatives essential for design continuity and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MM74HC4316N is determined by the following core parameters:

• Switch Circuit Configuration: Must be SPST - NO with 4 circuits (1:1 multiplexer/demultiplexer)
• Package Compatibility: Must be 16-DIP (0.300", 7.62mm) through-hole mounting
• Electrical Compatibility: Supply voltage ranges, on-state resistance, leakage current, and switching characteristics must support the intended application
• Pin-to-Pin Compatibility: Base product number 74HC4316 ensures functional equivalence

The CD74HC4316E, manufactured by Harris Corporation, meets the core substitution criteria of identical circuit configuration, package type, and base product number. However, differences in on-state resistance, supply voltage ranges, and switching speed must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the MM74HC4316N and CD74HC4316E are classified as obsolete products. Selection between these parts must account for the following documented differences:

On-State Resistance: The CD74HC4316E exhibits 170Ω maximum on-state resistance compared to 70Ω for the MM74HC4316N. Applications requiring lower signal attenuation or lower impedance paths should prioritize the MM74HC4316N where available.

Supply Voltage Range: The MM74HC4316N supports extended single-supply operation up to 12V, while the CD74HC4316E is limited to 6V single supply. Designs operating above 6V single supply require the MM74HC4316N.

Switching Speed: The MM74HC4316N provides faster switching times (14ns Ton, 20ns Toff) compared to the CD74HC4316E (37ns both). High-frequency signal routing applications benefit from the MM74HC4316N's superior speed performance.

Operating Temperature Range: The CD74HC4316E supports -55°C to 125°C operation, exceeding the MM74HC4316N's -40°C to 85°C range. Extended temperature applications may require the CD74HC4316E.

Compliance Status: The CD74HC4316E is documented as RoHS non-compliant. Both parts carry ECCN EAR99 classification and are unaffected by REACH regulations.

Frequently Asked Questions (FAQ)

Q: Can the CD74HC4316E directly replace the MM74HC4316N in existing designs?

A: Direct replacement is possible only if the application tolerates the documented parameter differences: higher on-state resistance (170Ω vs. 70Ω), slower switching times (37ns vs. 14ns/20ns), and reduced single-supply voltage range (6V maximum vs. 12V maximum). Pin-to-pin compatibility and package dimensions are identical.

Q: What applications are affected by the 100Ω on-state resistance difference?

A: Applications involving low-level analog signal switching, precision audio routing, or impedance-sensitive circuits may experience signal degradation with the CD74HC4316E's higher resistance. High-impedance load circuits are less affected than low-impedance applications.

Q: Are there supply voltage compatibility issues between these parts?

A: Yes. Designs operating at single-supply voltages above 6V require the MM74HC4316N. The CD74HC4316E is limited to 2V to 6V single supply. Dual-supply operation also differs: MM74HC4316N supports ±2V to ±6V, while CD74HC4316E supports ±1V to ±5V.

Q: How do switching speed differences impact circuit performance?

A: The MM74HC4316N's faster switching times (14ns Ton, 20ns Toff) are advantageous for high-frequency signal routing above 50MHz. The CD74HC4316E's 37ns switching times are suitable for applications below 50MHz. The CD74HC4316E offers higher -3dB bandwidth (200MHz vs. 100MHz), which may offset switching speed differences in some applications.

Q: Are both parts suitable for new designs?

A: Both parts are classified as obsolete. New designs should evaluate current-generation analog switch alternatives that offer active manufacturer support, improved specifications, and compliance with current standards.

Q: What is the significance of the 16-DIP package specification?

A: The 16-DIP (0.300", 7.62mm) package is a through-hole configuration suitable for breadboard prototyping, legacy PCB designs, and applications requiring manual component placement. Both parts are mechanically and electrically compatible in this package format.
