Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 74HC154D,652 is determined by the following critical parameters:

• Functional equivalence: 1 x 4:16 decoder/demultiplexer circuit configuration
• Output current capability: 5.2mA high and low output current
• Supply voltage range: 2V ~ 6V single supply operation
• Package compatibility: 24-SOIC surface mount form factor
• Compliance standards: ROHS3 compliance and REACH unaffected status

The substitute parts CD74HC154M and CD74HC154M96, both manufactured by Texas Instruments, meet all electrical and mechanical requirements for direct substitution. Both maintain the 74HC base product number designation, confirming functional equivalence within the 74HC logic family.

Parameter Comparison

Engineering Selection Recommendations

For applications currently using the 74HC154D,652, the CD74HC154M96 is the preferred substitute due to its active product status and extended availability. This part maintains full electrical and mechanical compatibility while offering superior long-term supply assurance.

The CD74HC154M represents an alternative with equivalent specifications but carries a Last Time Buy status, indicating limited future availability. Selection of this part should be evaluated against project timeline requirements.

Both Texas Instruments substitutes provide extended operating temperature range (-55°C to 125°C) compared to the original Nexperia part (-40°C to 125°C), offering improved performance margin in low-temperature applications.

Frequently Asked Questions (FAQ)

Q: Can CD74HC154M96 directly replace 74HC154D,652 in existing designs?

A: Yes. Both parts share identical circuit configuration (1 x 4:16 decoder), output current specifications (5.2mA), supply voltage range (2V ~ 6V), and 24-SOIC package dimensions. No design modifications are required.

Q: What is the difference between CD74HC154M and CD74HC154M96?

A: Both parts are functionally and electrically identical. The primary difference is packaging format: CD74HC154M is supplied in tube packaging, while CD74HC154M96 is supplied in cut tape and Digi-Reel format. Selection depends on procurement and assembly requirements.

Q: Does the extended temperature range of the substitute parts affect compatibility?

A: No. The substitute parts operate across -55°C to 125°C, which encompasses the original part's -40°C to 125°C range. This provides additional operational margin without affecting existing circuit performance.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. Both CD74HC154M and CD74HC154M96 are ROHS3 compliant and REACH unaffected, matching the compliance status of the original 74HC154D,652.

Q: Which substitute should be selected for new designs?

A: CD74HC154M96 is recommended for new designs due to active product status and established supply chain availability through multiple distribution channels.
