Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD74HC154M is determined by strict equivalence across the following critical parameters:

• Decoder/Demultiplexer type with 1 x 4:16 circuit configuration
• 24-SOIC surface mount package with identical 0.295" (7.50mm) width
• Single supply voltage range of 2V ~ 6V
• Output current specifications of 5.2mA high and 5.2mA low
• Operating temperature range of -55°C ~ 125°C
• ROHS3 compliance and MSL 1 rating

The substitute parts identified maintain full parametric equivalence across all electrical and mechanical specifications. Differences exist only in packaging format (tube versus cut tape/digi-reel) and product status (active versus last time buy).

Parameter Comparison

Engineering Selection Recommendations

CD74HC154M96 is the manufacturer-recommended substitute, offering identical electrical and mechanical specifications with active product status and availability in cut tape and digi-reel packaging formats. This part is suitable for new designs and ongoing production requiring extended component availability.

CD74HC4514M and CD74HC4515M are parametric equivalents maintaining full electrical and mechanical compatibility. Both parts carry last time buy status, similar to the primary part number. Selection between these alternatives should be based on current inventory availability and procurement lead times.

All substitute parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard manufacturing and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can CD74HC154M96 be used as a direct replacement for CD74HC154M?

A: Yes. CD74HC154M96 maintains identical electrical specifications, output current ratings, voltage supply range, operating temperature range, and 24-SOIC package dimensions. The only difference is packaging format (cut tape/digi-reel versus tube) and active product status.

Q: What is the difference between CD74HC4514M and CD74HC4515M?

A: Both parts are parametric equivalents with identical decoder/demultiplexer 1 x 4:16 circuit configuration, voltage supply, output current, operating temperature, and 24-SOIC package specifications. Differences exist only in base product number designation and individual inventory levels.

Q: Are all substitute parts compatible with the same PCB layout?

A: Yes. All substitute parts use the 24-SOIC package with 0.295" (7.50mm) width, ensuring identical pin spacing and footprint compatibility on existing circuit board designs.

Q: Does packaging format affect electrical performance?

A: No. Tube, cut tape, and digi-reel packaging formats are supply chain variations only. Electrical and mechanical specifications remain identical across all packaging options.

Q: Are all parts suitable for high-temperature applications?

A: Yes. All parts maintain the -55°C ~ 125°C operating temperature range, supporting applications across industrial and extended temperature environments.
