Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD74HCT597M is determined by the following critical parameters:

• Logic function: 8-bit shift register with parallel-to-serial conversion capability
• Package compatibility: 16-SOIC surface mount form factor with 0.154" width
• Electrical specifications: 4.5V to 5.5V supply voltage operation
• Output configuration: Push-pull output type
• Regulatory compliance: ROHS3 compliance and REACH unaffected status

The identified substitute parts maintain these core electrical and mechanical specifications, ensuring functional and physical interchangeability within the same circuit design. Packaging format differences (tube versus tape & reel) do not affect electrical performance but may impact procurement and handling procedures.

Parameter Comparison

Engineering Selection Recommendations

The CD74HCT597M is designated Last Time Buy status, necessitating transition to active alternatives. Both substitute parts maintain full electrical and mechanical compatibility with the original specification.

CD74HCT597M96 (Texas Instruments) represents the manufacturer-recommended direct substitute, maintaining identical electrical parameters and operating temperature range. This part is currently in active production status with 2000 units in stock.

74HCT597D,653 (Nexperia USA Inc.) provides an alternative from a qualified second-source manufacturer. This part operates across a narrower temperature range (-40°C to 125°C versus -55°C to 125°C) and is available in higher inventory (12895 units). Selection of this substitute requires confirmation that the -40°C minimum operating temperature meets application requirements.

Both substitutes carry ROHS3 compliance and REACH unaffected status, matching the regulatory profile of the original part.

Frequently Asked Questions (FAQ)

Q: Can CD74HCT597M96 be used as a direct replacement for CD74HCT597M?

A: Yes. CD74HCT597M96 maintains identical electrical specifications, operating temperature range, package configuration, and output characteristics. The difference in packaging format (tape & reel versus tube) does not affect electrical performance.

Q: What is the key difference between CD74HCT597M96 and 74HCT597D,653?

A: Both parts are electrically compatible 8-bit shift registers in 16-SOIC packages. The primary difference is the minimum operating temperature: CD74HCT597M96 operates from -55°C, while 74HCT597D,653 operates from -40°C. Applications requiring operation below -40°C must use CD74HCT597M96 or the original CD74HCT597M.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance and REACH unaffected status, matching the regulatory requirements of the original CD74HCT597M.

Q: Does packaging format affect circuit performance?

A: No. Tube and tape & reel packaging formats contain identical components and do not affect electrical performance, signal integrity, or functional operation. Packaging selection is determined by procurement and assembly process requirements.

Q: Which substitute part should be selected for new designs?

A: CD74HCT597M96 is the manufacturer-recommended substitute for new designs, offering active production status and full parameter compatibility. 74HCT597D,653 is suitable for applications where the -40°C minimum operating temperature is acceptable and second-source qualification is preferred.
