CD74HC4060PW Binary Counter 14-Bit Logic IC Equivalent & Substitute Parts

Part Overview

The CD74HC4060PW is a 14-bit binary counter logic IC manufactured by Texas Instruments in a 16-TSSOP surface mount package. This component functions as a negative edge-triggered counter with asynchronous reset capability, operating across a 2V to 6V supply voltage range with a maximum count rate of 35 MHz. The part is currently in Last Time Buy status, indicating production discontinuation. Identifying equivalent and substitute parts is necessary to ensure design continuity and maintain supply chain reliability for applications requiring this counter functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD74HC4060PW is determined by the following critical parameters that must remain constant across all equivalent parts:

• Logic Function: Binary counter with 14-bit capacity
• Bit Configuration: 1 element, 14 bits per element
• Trigger Mechanism: Negative edge-triggered operation
• Reset Functionality: Asynchronous reset capability
• Package Specification: 16-TSSOP form factor (0.173" width, 4.40mm)
• Voltage Compatibility: 2V to 6V supply range
• Mounting Technology: Surface mount configuration
• Base Product Series: 74HC logic family

Parts meeting these criteria are considered functionally equivalent. Variations in count rate performance, operating temperature range, product status, and manufacturer do not prevent substitution but may affect application suitability based on specific design requirements.

Parameter Comparison

Engineering Selection Recommendations

CD74HC4060PWR (Texas Instruments) is the primary recommended substitute. This part maintains identical electrical specifications to the CD74HC4060PW while offering Active product status, ensuring continued availability and manufacturer support. The transition from Tube to Cut Tape & Digi-Reel packaging provides supply chain flexibility without functional impact.

74HC4060PW,118 (Nexperia USA Inc.) serves as an alternative substitute with higher count rate performance (95 MHz versus 35 MHz). This part is suitable for applications where increased timing margin is beneficial. Operating temperature range is reduced to -40°C to 125°C, which may limit use in extended temperature environments.

M74HC4060YTTR (STMicroelectronics) is qualified to AEC-Q100 automotive standards and carries Automotive grade designation. This part is appropriate for automotive and mission-critical applications requiring formal qualification documentation. Count rate is 65 MHz with -40°C to 125°C operating range.

MC74HC4060ADTR2G (onsemi) maintains the full -55°C to 125°C operating temperature range matching the original part. Product status is Active with 50 MHz count rate performance. This part provides temperature range continuity for extended environment applications.

MC74HC4060ADTG (onsemi) is marked Obsolete and should be avoided for new designs despite current inventory availability.

Frequently Asked Questions (FAQ)

Q: Can I substitute CD74HC4060PW with CD74HC4060PWR? A: Yes. Both parts are functionally equivalent 14-bit binary counters in 16-TSSOP packages with identical electrical specifications. The primary difference is packaging format (Tube versus Cut Tape & Digi-Reel) and product status (Last Time Buy versus Active). CD74HC4060PWR is recommended for new applications.

Q: What is the significance of count rate differences among substitute parts? A: Count rate represents maximum switching frequency. The CD74HC4060PW operates at 35 MHz, while substitutes range from 50 MHz to 95 MHz. Higher count rates provide timing margin but do not affect functional compatibility. Selection depends on application timing requirements.

Q: Are there temperature range limitations I should consider? A: The original CD74HC4060PW operates from -55°C to 125°C. Nexperia and STMicroelectronics substitutes are limited to -40°C to 125°C. If your application requires operation below -40°C, select CD74HC4060PWR or MC74HC4060ADTR2G, which maintain the full -55°C to 125°C range.

Q: What does AEC-Q100 qualification mean for the M74HC4060YTTR? A: AEC-Q100 is an automotive industry qualification standard. The M74HC4060YTTR meets this specification, making it suitable for automotive applications where formal qualification is required. Non-automotive applications do not require this qualification.

Q: Does packaging format affect electrical performance? A: No. Tube, Cut Tape & Digi-Reel, and Tape & Reel are distribution formats only. Electrical specifications and performance remain identical. Packaging selection is based on assembly process requirements and supply chain preferences.

Q: Can I use 74HC4060PW,118 in place of CD74HC4060PW in all applications? A: Functionally yes, with one consideration: the Nexperia part has a reduced operating temperature range (-40°C to 125°C versus -55°C to 125°C). If your application operates below -40°C, this substitute is not appropriate. Otherwise, the higher count rate (95 MHz) provides additional timing margin.

Q: Why is MC74HC4060ADTG listed as Obsolete? A: MC74HC4060ADTG is marked Obsolete by the manufacturer, indicating production has ended. Although inventory may be available, this part should not be selected for new designs. Use MC74HC4060ADTR2G instead, which is the Active equivalent from onsemi.
