Substitute Part Grouping Explanation

Substitution eligibility for the 74HC4316N,652 is determined by the following critical parameters:

Switch Circuit Configuration: Must be SPST - NO (Single Pole Single Throw - Normally Open)
Circuit Count: Must contain 4 independent circuits
Multiplexer/Demultiplexer Ratio: Must be 1:1
Package Type: Must be 16-DIP (0.300", 7.62mm) for mechanical and electrical compatibility
Mounting Type: Must be Through Hole
Supply Voltage Compatibility: Acceptable overlap in single or dual supply voltage ranges
Operating Temperature Range: Must support the required application temperature window

The CD74HC4316E from Harris Corporation meets these core substitution criteria, sharing identical switch circuit topology, circuit count, multiplexer configuration, and package format. Variations in on-state resistance, switching speed, and supply voltage limits represent acceptable parameter differences within the IC switch component category.

Engineering Selection Recommendations

74HC4316N,652 (NXP Semiconductors)

This part is ROHS3 compliant and REACH unaffected, making it suitable for applications with environmental compliance requirements. The lower on-state resistance (135Ω) and faster switching times (16ns) provide performance advantages in signal-switching applications requiring minimal insertion loss and rapid response. However, the restricted single supply voltage range (2V ~ 10V) compared to the substitute may limit flexibility in certain dual-supply system designs.

CD74HC4316E (Harris Corporation)

This substitute part is RoHS non-compliant and should be evaluated against specific regulatory requirements for the target application. The higher on-state resistance (170Ω) and slower switching times (37ns) represent measurable performance trade-offs. The extended operating temperature range (-55°C ~ 125°C) provides broader thermal coverage. The narrower single supply voltage range (2V ~ 6V) requires verification against system power supply specifications.

Both parts share identical package geometry, circuit topology, and core functional characteristics. Selection between them depends on compliance requirements, performance specifications, and supply voltage constraints of the target application.

Frequently Asked Questions (FAQ)

Q: Can CD74HC4316E directly replace 74HC4316N,652 in existing designs?

A: Mechanical and functional compatibility exists due to identical 16-DIP package format, SPST-NO switch configuration, and 1:1 multiplexer topology. However, parameter differences in on-state resistance (135Ω vs. 170Ω), switching speed (16ns vs. 37ns), and supply voltage ranges require circuit-level evaluation. RoHS compliance status differs between parts.

Q: What are the critical differences in electrical performance?

A: The 74HC4316N,652 offers lower on-state resistance and faster switching times, resulting in reduced signal insertion loss and faster response. The CD74HC4316E provides higher bandwidth (200MHz vs. 160MHz) and extended temperature range (-55°C vs. -40°C minimum). On-state resistance difference of 35Ω may impact signal integrity in high-impedance or precision analog applications.

Q: Are both parts suitable for high-frequency signal switching?

A: Both parts support signal switching within their specified bandwidth limits. The 74HC4316N,652 operates to 160MHz; the CD74HC4316E to 200MHz. Selection depends on specific frequency requirements and acceptable insertion loss at the target frequency.

Q: What packaging considerations apply to through-hole mounting?

A: Both parts use identical 16-DIP (0.300", 7.62mm) through-hole package format. PCB footprints, lead spacing, and mounting procedures are interchangeable. Verify PCB design files support standard 0.300" DIP spacing.

Q: How do supply voltage ranges affect substitution decisions?

A: The 74HC4316N,652 supports single supply from 2V to 10V; the CD74HC4316E from 2V to 6V. Designs operating above 6V single supply require the NXP part. Both support dual supply operation (±1V ~ 5V). Verify system power supply specifications before substitution.

Q: What is the impact of RoHS compliance differences?

A: The 74HC4316N,652 is ROHS3 compliant; the CD74HC4316E is RoHS non-compliant. Applications subject to RoHS regulations, EU directives, or customer compliance requirements must use the NXP part or verify exemptions with regulatory documentation.
