74HC75D,653 Equivalent & Substitute Parts

Part Overview

The 74HC75D,653 is a D-Type Transparent Latch logic integrated circuit manufactured by Nexperia USA Inc. in a 16-SOIC surface mount package. This component functions as a dual 2-bit transparent latch with differential output, designed for digital logic applications requiring data storage and control. The part is currently in active production status with 2601 units available in new original inventory.

Substitute parts become necessary when the primary part reaches end-of-life status, experiences supply constraints, or when design requirements allow for compatible alternatives that meet the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 74HC75D,653 is determined by strict adherence to the following parameters:

Critical Matching Parameters:

• Logic Type: D-Type Transparent Latch
• Circuit Configuration: 2:2 (2 Channel)
• Output Type: Differential
• Supply Voltage Range: 2V to 6V
• Independent Circuits: 2
• Package Type: 16-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount

Allowable Variations:

• Propagation Delay Time: Up to 10ns (faster than or equal to 11ns)
• Operating Temperature Range: Extended ranges (-55°C to 125°C) are acceptable
• Packaging Format: Tape & Reel (TR) or Tube
• Product Status: Active, Obsolete, or Last Time Buy
• RoHS Compliance: ROHS3 Compliant or RoHS non-compliant

The following parts meet these substitution criteria: CD74HC75M, CD74HC75M96, and CD74HC75MT.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: 74HC75D,653 (Nexperia) This part is the recommended choice for new designs. It maintains active production status, full ROHS3 compliance, and meets all specified electrical and mechanical requirements.

Secondary Selection: CD74HC75M96 (Texas Instruments) This substitute is suitable for applications where the primary part is unavailable. It offers active product status, ROHS3 compliance, and identical electrical performance with faster propagation delay (10ns). Tape & Reel packaging matches the primary part format.

Tertiary Selection: CD74HC75MT (Texas Instruments) This substitute is acceptable for existing designs requiring component replacement. Although marked as Last Time Buy, it provides ROHS3 compliance and extended operating temperature range (-55°C to 125°C). Tape & Reel packaging is compatible with production processes.

Not Recommended: CD74HC75M (Harris Corporation) This part is obsolete and RoHS non-compliant. While electrically compatible, its obsolete status and lack of RoHS3 compliance make it unsuitable for new designs or long-term supply planning.

Frequently Asked Questions (FAQ)

Q: Can CD74HC75M96 be used as a direct replacement for 74HC75D,653? A: Yes. Both parts share identical logic type, circuit configuration, output type, supply voltage range, independent circuits, package type, and mounting type. The CD74HC75M96 offers faster propagation delay (10ns versus 11ns), which is a performance improvement.

Q: What is the difference between Tape & Reel and Tube packaging? A: Tape & Reel (TR) packaging is used for automated assembly processes and high-volume production. Tube packaging is used for manual assembly or lower-volume applications. Both formats contain the same component; the difference is in handling and storage method.

Q: Why is CD74HC75M marked as obsolete? A: Obsolete status indicates the manufacturer has discontinued production. While the part may remain available through inventory channels, it is not recommended for new designs due to uncertain long-term availability.

Q: Does RoHS3 compliance matter for my application? A: RoHS3 compliance is mandatory for products sold in the European Union and many other regions. If your application requires export to these markets or compliance with environmental regulations, ROHS3-compliant parts are necessary.

Q: Are the substitute parts pin-compatible with 74HC75D,653? A: Yes. All substitute parts use the 16-SOIC package with identical pin configuration and electrical characteristics, ensuring direct PCB compatibility.

Q: What is the significance of the extended operating temperature range (-55°C to 125°C) in CD74HC75M96 and CD74HC75MT? A: The extended lower temperature limit (-55°C versus -40°C) allows these parts to operate in more extreme cold environments. This is an enhancement over the primary part and does not restrict their use in standard temperature applications.
