CD74AC74M96G4 Equivalent & Substitute Parts

Part Overview

The CD74AC74M96G4 is a dual D-type flip-flop logic integrated circuit manufactured by Texas Instruments in a 14-SOIC surface mount package. This component is classified as obsolete, which necessitates identification of active equivalent and substitute parts for ongoing design support and procurement.

The CD74AC74M96G4 provides two independent D-type flip-flops with complementary outputs, set/preset and reset functions, and positive edge triggering. It operates across a supply voltage range of 1.5V to 5.5V with a maximum propagation delay of 10ns at 5V with 50pF load.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD74AC74M96G4 is determined by the following critical parameters:

Functional Equivalence: All substitute parts must be dual D-type flip-flops with complementary outputs, positive edge triggering, and set/preset and reset functions.

Package Compatibility: All substitutes must use the 14-SOIC (0.154", 3.90mm Width) surface mount package to ensure direct PCB compatibility without layout modifications.

Electrical Compatibility: Substitute parts must operate within overlapping supply voltage ranges and maintain compatible propagation delay characteristics. Output drive capability (24mA) and quiescent current specifications must be met.

Compliance Requirements: All substitutes must maintain ROHS3 compliance and MSL 1 rating to ensure manufacturing and storage compatibility.

The substitute parts identified are grouped into two categories:

Category 1 - Texas Instruments Active Equivalent: CD74AC74M96 (Tape & Reel packaging variant of the same base product)

Category 2 - onsemi Cross-Manufacturer Equivalents: MC74AC74DR2G, MC74AC74DG, and NLV74AC74DR2G, all sharing the 74AC74 base product number and identical functional specifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation - CD74AC74M96: This Texas Instruments part is the direct active equivalent with identical electrical specifications and operating temperature range (-55°C ~ 125°C). It maintains the same supply voltage range (1.5V ~ 5.5V) and propagation delay characteristics. The only difference is packaging format (Tape & Reel versus Tube). This part is recommended for applications requiring the extended temperature range and original manufacturer continuity.

Secondary Recommendation - MC74AC74DR2G or MC74AC74DG: These onsemi parts are functionally equivalent with higher clock frequency capability (160 MHz versus 110 MHz) and lower input capacitance (4.5 pF versus 10 pF). However, they operate at a reduced temperature range (-40°C ~ 85°C) and require a minimum supply voltage of 2V. MC74AC74DR2G is supplied in Tape & Reel format, while MC74AC74DG is supplied in Tube format. These parts are suitable for applications not requiring the extended low-temperature operation of the original part.

Alternative - NLV74AC74DR2G: This onsemi part is classified as obsolete and carries a higher quiescent current specification (40 µA versus 4 µA). It is not recommended for new designs due to its obsolete status and inferior power consumption characteristics.

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

Frequently Asked Questions (FAQ)

Q: Can CD74AC74M96 directly replace CD74AC74M96G4 in existing designs?

A: Yes. CD74AC74M96 is the active equivalent with identical electrical specifications and operating temperature range. The difference is packaging format (Tape & Reel versus Tube), which does not affect circuit functionality. PCB layout and schematic remain unchanged.

Q: What are the key differences between Texas Instruments and onsemi substitutes?

A: Texas Instruments CD74AC74M96 maintains the original supply voltage range (1.5V ~ 5.5V) and operating temperature range (-55°C ~ 125°C). onsemi MC74AC74DR2G and MC74AC74DG operate at 2V ~ 6V supply voltage and -40°C ~ 85°C temperature range. The onsemi parts offer higher clock frequency (160 MHz) and lower input capacitance (4.5 pF). Selection depends on application temperature and voltage requirements.

Q: Are the 14-SOIC packages identical across all substitute parts?

A: Yes. All parts use the 14-SOIC (0.154", 3.90mm Width) surface mount package. Pin configuration and PCB footprint are identical, allowing direct substitution without layout modifications.

Q: Why is NLV74AC74DR2G listed as a substitute if it is obsolete?

A: NLV74AC74DR2G is included for reference in applications where it may already be in use. However, it is not recommended for new designs due to its obsolete status and higher quiescent current (40 µA versus 4 µA), which increases power consumption.

Q: What compliance certifications apply to all substitute parts?

A: All parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating. This ensures compatibility with standard manufacturing processes and storage conditions without special handling requirements.

Q: Which substitute part should be selected for low-temperature applications below -40°C?

A: CD74AC74M96 from Texas Instruments is the only substitute that maintains operation down to -55°C. onsemi parts (MC74AC74DR2G, MC74AC74DG) are limited to -40°C minimum operating temperature.
