CD74HC4060PWT 14-Bit Binary Counter Equivalent & Substitute Parts

Part Overview

The CD74HC4060PWT is a 14-bit binary counter IC manufactured by Texas Instruments in a 16-TSSOP surface mount package. This logic component functions as a negative edge-triggered counter with asynchronous reset capability, operating across a 2V to 6V supply range. The part is currently in Last Time Buy status, indicating end-of-life production. Identifying equivalent and substitute parts ensures design continuity and supply chain flexibility for applications requiring 14-bit binary counting functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD74HC4060PWT is determined by strict equivalence across the following critical parameters:

• Logic Type: Binary Counter (1 element, 14-bit configuration)
• Trigger Mechanism: Negative Edge
• Reset Function: Asynchronous
• Count Direction: Up
• Package: 16-TSSOP form factor
• Voltage Supply: 2V to 6V range
• Mounting: Surface Mount

All identified substitute parts maintain these core electrical and mechanical specifications. Variations in count rate (35 MHz to 95 MHz) and operating temperature ranges represent performance enhancements or application-specific qualifications that do not affect functional substitutability. Packaging format differences (Tape & Reel versus Cut Tape) reflect distribution methods only and do not impact electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

For new designs and ongoing production, CD74HC4060PWR (Texas Instruments, Active status) provides direct electrical and mechanical equivalence with improved supply availability. This part maintains identical electrical specifications while offering superior inventory levels and active product status.

MC74HC4060ADTR2G (onsemi, Active) and 74HC4060PW,118 (Nexperia USA Inc., Active) serve as qualified alternatives with enhanced count rate performance (50 MHz and 95 MHz respectively), suitable for applications requiring higher frequency operation within the same 2V to 6V supply envelope.

M74HC4060YTTR (STMicroelectronics, Active) includes automotive-grade qualification (AEC-Q100) and is appropriate for automotive and harsh environment applications requiring extended temperature stability to -40°C minimum.

MC74HC4060ADTG (onsemi, Obsolete) should not be selected for new designs due to end-of-life status, despite current inventory availability.

All substitute parts maintain ROHS3 compliance, MSL Level 1 rating, and identical 16-TSSOP package geometry, ensuring PCB layout and thermal management compatibility.

Frequently Asked Questions (FAQ)

Q: Can CD74HC4060PWT be directly replaced with CD74HC4060PWR?

A: Yes. Both parts are manufactured by Texas Instruments with identical electrical specifications. The difference is packaging format: CD74HC4060PWT uses Tape & Reel distribution, while CD74HC4060PWR uses Cut Tape & Digi-Reel®. Electrical performance and pinout are equivalent.

Q: What is the significance of count rate differences among substitute parts?

A: Count rate (35 MHz to 95 MHz) indicates maximum clock frequency capability. All parts meet or exceed the original 35 MHz specification. Higher count rates provide performance margin for applications with demanding timing requirements but do not affect functional compatibility in lower-frequency circuits.

Q: Are automotive-qualified parts suitable for non-automotive applications?

A: Yes. M74HC4060YTTR (AEC-Q100 qualified) meets automotive standards and exceeds general industrial requirements. It is suitable for any application requiring the 14-bit binary counter function, with the added benefit of enhanced temperature stability and reliability screening.

Q: Does operating temperature range affect substitutability?

A: Operating temperature range defines the guaranteed functional envelope. Parts rated -55°C to 125°C are suitable for applications requiring -40°C to 125°C operation. Parts rated -40°C to 125°C are not suitable for applications requiring operation below -40°C. Verify application temperature requirements before selection.

Q: Why is MC74HC4060ADTG listed despite obsolete status?

A: MC74HC4060ADTG is documented for reference and historical traceability. Current inventory exists but is limited (727 pcs). New designs should not incorporate obsolete parts; active alternatives provide superior long-term supply assurance.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed parts maintain ROHS3 compliance and MSL Level 1 moisture sensitivity rating, meeting environmental and reliability standards for commercial and industrial applications.
