Substitute Part Grouping Explanation

Substitution for the CD74AC04M96G4 is determined by the following critical parameters:

Logic Function: All substitutes must be 6-channel inverter ICs with single input configuration
Package Type: All substitutes must use 14-SOIC surface mount packaging with identical physical dimensions
Supply Voltage Compatibility: Substitutes must operate within overlapping voltage ranges
Output Drive Capability: Output current specifications must match or exceed 24mA for both high and low states
Propagation Delay: Maximum delay specifications must support the same timing requirements
Compliance: All substitutes must maintain ROHS3 compliance and equivalent environmental certifications

The CD74AC04M96 (Texas Instruments) is a parametric equivalent with identical electrical specifications. The onsemi alternatives (74AC04SC, 74AC04SCX, MC74AC04DG, MC74AC04DR2G) are manufacturer-recommended substitutes with compatible but slightly different operating ranges and temperature specifications.

Engineering Selection Recommendations

CD74AC04M96 (Texas Instruments): This is the direct parametric equivalent with identical electrical specifications and extended temperature range (-55°C to 125°C). It maintains the same supply voltage range (1.5V to 5.5V) and propagation delay characteristics. This part is currently active and represents the primary replacement for the obsolete CD74AC04M96G4.

74AC04SCX (onsemi): This substitute offers the highest inventory availability (47,750 pcs) and is supplied in Cut Tape & Digi-Reel packaging. It operates within a 2V to 6V supply range with 7ns propagation delay. The reduced quiescent current (2 µA) provides lower power consumption. Operating temperature range is -40°C to 85°C, which is narrower than the original part.

MC74AC04DR2G (onsemi): This alternative provides the second-highest inventory (55,500 pcs) and matches the quiescent current specification (4 µA) of the original part. It operates within 2V to 6V supply range with 7ns propagation delay and -40°C to 85°C temperature range.

74AC04SC (onsemi): Supplied in tube packaging with 2,200 pcs available. Specifications match MC74AC04DR2G and 74AC04SCX with 2 µA quiescent current and -40°C to 85°C operating range.

MC74AC04DG (onsemi): Tube-packaged alternative with 2,916 pcs in stock. Maintains 4 µA quiescent current matching the original specification, with 2V to 6V supply range and -40°C to 85°C operating temperature.

All substitutes maintain ROHS3 compliance and equivalent environmental certifications. Selection should prioritize the CD74AC04M96 for designs requiring the extended temperature range and original voltage specifications, or onsemi alternatives where supply voltage range of 2V to 6V and operating temperature of -40°C to 85°C are acceptable.

Frequently Asked Questions (FAQ)

Q: Can the onsemi 74AC04 variants directly replace the CD74AC04M96G4?

A: Yes, all listed onsemi parts are functionally compatible substitutes. They maintain identical logic function, circuit count, input configuration, output drive capability, and 14-SOIC packaging. Differences exist in supply voltage range (2V to 6V versus 1.5V to 5.5V), operating temperature range (-40°C to 85°C versus -55°C to 125°C), and propagation delay (7ns versus 6.5ns). Verify these parameters against your application requirements before selection.

Q: What is the difference between the Texas Instruments CD74AC04M96 and CD74AC04M96G4?

A: The CD74AC04M96G4 is obsolete while CD74AC04M96 is active. Both share identical electrical specifications, including supply voltage (1.5V to 5.5V), quiescent current (4 µA), output drive (24mA), and propagation delay (6.5ns at 5V, 50pF). The CD74AC04M96 is the recommended replacement for the obsolete variant.

Q: How do packaging options differ among the substitutes?

A: CD74AC04M96 is available in Cut Tape & Digi-Reel packaging. onsemi alternatives are supplied in either Tube (74AC04SC, MC74AC04DG) or Cut Tape & Digi-Reel (74AC04SCX, MC74AC04DR2G) formats. All maintain identical 14-SOIC physical dimensions (0.154", 3.90mm width). Packaging selection depends on procurement volume and assembly requirements.

Q: Are there temperature range limitations with onsemi substitutes?

A: Yes. onsemi variants operate from -40°C to 85°C, compared to the original CD74AC04M96G4 range of -55°C to 125°C. If your application requires operation below -40°C or above 85°C, the Texas Instruments CD74AC04M96 is the appropriate choice.

Q: What is the propagation delay difference between the original and onsemi substitutes?

A: The CD74AC04M96G4 specifies 6.5ns maximum propagation delay at 5V with 50pF load. onsemi alternatives specify 7ns under identical conditions. This 0.5ns difference is within typical logic IC tolerances and should not impact most applications. Verify timing margins in your specific circuit design.

Q: Do all substitutes maintain the same quiescent current specification?

A: No. The original CD74AC04M96G4 and onsemi MC74AC04DG and MC74AC04DR2G specify 4 µA maximum quiescent current. The onsemi 74AC04SC and 74AC04SCX specify 2 µA, offering lower power consumption. Select based on your power budget requirements.
