CD4516BCN Binary Counter IC Equivalent & Substitute Parts

Part Overview

The CD4516BCN is a 4-bit binary counter IC from the 4000B logic series manufactured by onsemi. This device functions as a synchronous counter with asynchronous reset, capable of counting up or down at a maximum rate of 11 MHz. The CD4516BCN is classified as obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and new design implementations where this logic function is required.

Substitute Part Grouping Explanation

Substitute parts for the CD4516BCN are identified based on functional equivalence within the 4000B logic series. The primary substitution criterion is the base product number CD4516, which defines the core counter architecture and electrical characteristics. All substitute parts must maintain the following critical parameters:

• 4-bit binary counter with up/down counting capability
• Asynchronous reset functionality
• Synchronous timing operation
• 11 MHz maximum count rate
• Positive edge trigger
• Supply voltage compatibility within the specified range
• Identical logic type and element configuration

The CD4516BE from Texas Instruments qualifies as a direct substitute based on these functional parameters. Packaging and mounting type differences do not affect the core logic function and are secondary considerations in substitution decisions.

Parameter Comparison

Engineering Selection Recommendations

The CD4516BE from Texas Instruments is a functional equivalent to the CD4516BCN. Both devices share identical core logic specifications and operate within compatible electrical parameters. The CD4516BE offers extended operating temperature range (-55°C to 125°C versus -40°C to 85°C) and expanded supply voltage tolerance (3 V to 18 V versus 3 V to 15 V), providing greater flexibility in system design applications.

The CD4516BE is classified as active product status, ensuring continued availability and manufacturing support. This device meets ROHS3 compliance requirements, whereas the CD4516BCN is RoHS non-compliant. For new designs or systems requiring regulatory compliance, the CD4516BE is the appropriate selection.

Both parts are classified under ECCN EAR99 and share identical HTSUS coding (8542.39.0001), confirming their equivalence for export and procurement purposes.

Frequently Asked Questions (FAQ)

Q: Can the CD4516BE directly replace the CD4516BCN in existing designs?

A: Yes. Both devices implement identical 4-bit binary counter logic with up/down counting, asynchronous reset, and 11 MHz count rate. The CD4516BE operates within the CD4516BCN supply voltage range and maintains functional compatibility across all counter operations.

Q: What are the packaging differences between these parts?

A: The CD4516BCN packaging is not specified in the available data. The CD4516BE is supplied in 16-PDIP (0.300", 7.62mm) through-hole package. Verify the original CD4516BCN package type before substitution to ensure mechanical compatibility with existing PCB layouts.

Q: Does the extended temperature range of the CD4516BE affect compatibility?

A: No. The CD4516BE operating temperature range of -55°C to 125°C encompasses the CD4516BCN range of -40°C to 85°C. Extended temperature capability does not impact functional compatibility in applications operating within the original temperature specifications.

Q: Is the CD4516BE suitable for new product designs?

A: Yes. The CD4516BE is active product status with ROHS3 compliance, making it appropriate for new designs. The CD4516BCN is obsolete and should not be specified for new development.

Q: Are there supply voltage considerations when substituting?

A: The CD4516BE accepts 3 V to 18 V supply, which exceeds the CD4516BCN specification of 3 V to 15 V. Both devices operate correctly within the original 3 V to 15 V range. If your system operates above 15 V, the CD4516BE provides additional margin.
