Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD74HC373M96 is determined by the following critical parameters:

Primary Substitution Criteria:

• Logic Type: D-Type Transparent Latch
• Circuit Configuration: 8:8
• Output Type: Tri-State
• Voltage Supply Range: 2V ~ 6V
• Package / Case: 20-SOIC (0.295", 7.50mm Width)
• Mounting Type: Surface Mount

Secondary Considerations:

• Propagation Delay Time: Acceptable range 12ns ~ 30ns
• Operating Temperature Range: Minimum -40°C to -55°C; Maximum 85°C to 125°C
• Current Output Specifications: 7.8mA High/Low
• RoHS Compliance: ROHS3 Compliant
• Moisture Sensitivity Level: MSL 1 or MSL 3

Substitute parts are grouped into two categories: Parametric Equivalents (CD74HC573M96, MC74HC573ADWR2G) which share identical base functionality with different latch types, and Direct Manufacturer Equivalents (MC74HC373ADWR2G, 74HC373D,653, 74HC373D-Q100,118, MC74HC373ADWG, MM74HC373WM, MM74HC373WMX) which maintain the same 74HC373 base product number across different manufacturers and packaging options.

Engineering Selection Recommendations

For Direct Pin-Compatible Replacement: Select MC74HC373ADWR2G, 74HC373D,653, or 74HC373D-Q100,118 when identical 74HC373 base product functionality is required. These parts maintain full electrical and mechanical compatibility with the CD74HC373M96.

For Extended Temperature Range Applications: The CD74HC373M96, CD74HC573M96, MC74HC373ADWR2G, and MC74HC373ADWG support the full -55°C to 125°C operating range. Parts such as MM74HC373WM and MM74HC373WMX are limited to -40°C to 85°C and are suitable only for applications within this narrower range.

For Automotive Applications: The 74HC373D-Q100,118 is qualified to AEC-Q100 automotive standards and carries Nexperia USA Inc. manufacturer designation, making it the appropriate selection for automotive-grade requirements.

For Moisture Sensitivity Considerations: The CD74HC373M96 features MSL 1 (Unlimited) moisture sensitivity, providing maximum handling flexibility. Substitute parts with MSL 3 (168 Hours) such as MC74HC373ADWR2G, MC74HC373ADWG, and MM74HC373WMX require controlled storage and handling within 168-hour exposure windows.

For Propagation Delay Performance: Parts with faster propagation delays (12ns to 21ns) such as 74HC373D,653, 74HC373D-Q100,118, MC74HC373ADWR2G, and MC74HC373ADWG offer improved timing performance compared to the CD74HC373M96 (30ns) and are suitable for timing-critical applications.

Frequently Asked Questions (FAQ)

Q: Can I use CD74HC573M96 as a direct substitute for CD74HC373M96? A: CD74HC573M96 is a parametric equivalent sharing identical electrical specifications (voltage, current, propagation delay, operating temperature, and package). The primary difference is the base product number (74HC573 versus 74HC373), which indicates a different latch type. Verify your circuit design requirements for latch functionality compatibility before substitution.

Q: What is the difference between 74HC373D,653 and 74HC373D-Q100,118? A: Both parts are manufactured by Nexperia USA Inc. with identical electrical specifications. The 74HC373D-Q100,118 carries AEC-Q100 automotive qualification and is supplied in Tape & Reel packaging, while 74HC373D,653 is supplied in Cut Tape & Digi-Reel® packaging. Select 74HC373D-Q100,118 for automotive applications requiring qualification documentation.

Q: Are onsemi MC74HC373ADWR2G and MC74HC373ADWG interchangeable? A: Both onsemi parts share identical electrical specifications (21ns propagation delay, -55°C to 125°C operating range, MSL 3). The primary difference is packaging: MC74HC373ADWR2G is supplied in Cut Tape & Digi-Reel®, while MC74HC373ADWG is supplied in Tube. Select based on your assembly process requirements.

Q: Why do some substitute parts have faster propagation delays? A: Propagation delay variation (12ns to 30ns) reflects manufacturing process differences across vendors. Faster delays indicate improved timing performance. Verify that your circuit design does not depend on the original 30ns delay specification before selecting faster alternatives.

Q: Can I use MM74HC373WM or MM74HC373WMX in applications requiring -55°C operation? A: No. Both MM74HC373WM and MM74HC373WMX are limited to -40°C minimum operating temperature. For applications requiring -55°C operation, select CD74HC373M96, CD74HC573M96, MC74HC373ADWR2G, MC74HC373ADWG, or MC74HC573ADWR2G.

Q: What does MSL 3 (168 Hours) mean for component handling? A: MSL 3 indicates the component must be used within 168 hours of package opening under controlled humidity conditions. Parts with MSL 1 (Unlimited) such as CD74HC373M96 have no time-based storage restrictions after opening. Plan inventory and assembly scheduling accordingly when using MSL 3 components.

Q: Are all substitute parts ROHS3 compliant? A: Most substitute parts are ROHS3 compliant. MM74HC373WM does not specify RoHS status in available documentation. Verify RoHS compliance requirements for your application before final part selection.
