MC74HC4060ADT Equivalent & Substitute Parts

Part Overview

The MC74HC4060ADT is a 14-bit binary counter logic IC manufactured by onsemi in a 16-TSSOP surface mount package. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications. The MC74HC4060ADT operates as a negative edge-triggered counter with asynchronous reset, suitable for digital counting and frequency division circuits across industrial and commercial applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the MC74HC4060ADT is determined by strict equivalence across the following critical parameters: base product number (74HC4060), logic type (binary counter), bit width (14-bit), trigger mechanism (negative edge), reset configuration (asynchronous), supply voltage range (2 V ~ 6 V), and package type (16-TSSOP surface mount). Parts meeting these criteria are classified as direct or similar substitutes based on manufacturer, product status, and compliance certifications. Count rate variations and operating temperature ranges are noted but do not disqualify substitution when other parameters align. Package variants (16-TSSOP versus 16-SSOP) are identified separately due to mechanical differences.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring active product status with full compliance, CD74HC4060PWR (Texas Instruments) and SN74HC4060PWR (Texas Instruments) are preferred selections. Both parts are actively manufactured, ROHS3 compliant, and maintain the 16-TSSOP package footprint compatible with MC74HC4060ADT PCB layouts.

For automotive-grade applications requiring AEC-Q100 qualification, 74HC4060PW-Q100,11 (Nexperia USA Inc.) is the designated substitute. This part delivers the highest count rate specification at 95 MHz and maintains active product status.

MC74HC4060ADTG (onsemi) provides a direct manufacturer alternative with ROHS3 compliance while retaining the original onsemi manufacturing source. This part is classified as obsolete but remains available in inventory.

SN74HC4060DBR (Texas Instruments) uses a 16-SSOP package variant instead of 16-TSSOP. This package difference requires PCB layout modification and is suitable only when mechanical constraints permit package substitution.

Parts with Last Time Buy status (CD74HC4060PW, CD74HC4060PWT, SN74HC4060PW, SN74HC4060PWT) are available in current inventory but represent end-of-life products. These selections are appropriate for legacy system maintenance only.

Frequently Asked Questions (FAQ)

Q: Can I substitute SN74HC4060DBR for MC74HC4060ADT without PCB modification?

A: No. SN74HC4060DBR uses a 16-SSOP package (0.209", 5.30mm width) while MC74HC4060ADT uses 16-TSSOP (0.173", 4.40mm width). Package footprints are not interchangeable. PCB layout modification is required.

Q: What is the difference between 74HC4060PW,118 and 74HC4060PW-Q100,11?

A: Both are Nexperia parts with identical electrical specifications and 16-TSSOP packaging. The primary difference is that 74HC4060PW-Q100,11 carries AEC-Q100 automotive qualification and is supplied in Tape & Reel packaging, while 74HC4060PW,118 is supplied in Cut Tape & Digi-Reel format without automotive qualification.

Q: Why do Texas Instruments parts show lower count rates (33-35 MHz) compared to the original MC74HC4060ADT (50 MHz)?

A: Count rate specifications vary by manufacturer design and process technology. All parts meet the functional requirement of negative edge-triggered 14-bit binary counting within the 2 V ~ 6 V supply range. Lower count rate specifications do not prevent functional substitution in applications operating below the specified maximum frequency.

Q: Is MC74HC4060ADTG a direct replacement for MC74HC4060ADT?

A: MC74HC4060ADTG is a direct onsemi equivalent with identical electrical and mechanical specifications. The primary difference is ROHS3 compliance certification. Both parts use 16-TSSOP packaging and are pin-compatible.

Q: Which substitute part has the longest available product lifecycle?

A: CD74HC4060PWR and SN74HC4060PWR maintain active product status with no announced end-of-life date. These parts are recommended for new designs requiring long-term availability assurance.

Q: Can I use parts with -40°C ~ 85°C operating temperature in applications requiring -55°C ~ 125°C range?

A: No. Operating temperature range is a critical specification. Parts rated -40°C ~ 85°C (SN74HC4060 series) cannot be substituted in applications requiring the full -55°C ~ 125°C range. Use CD74HC4060 series or MC74HC4060ADTG for extended temperature applications.
