Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD74ACT541EG4 is determined by strict alignment of the following electrical and mechanical parameters:

• Logic type and function (Buffer, Non-Inverting)
• Element and bit configuration (1 Element, 8 Bits per Element)
• Output architecture (3-State)
• Output current specifications (24mA, 24mA)
• Supply voltage range (4.5V ~ 5.5V)
• Operating temperature range (-55°C ~ 125°C)
• Package form factor (20-DIP)
• Mounting technology (Through Hole)
• Base product number (74ACT541)

The CD74ACT541E, manufactured by Harris Corporation, meets all substitution criteria within these parameters.

Parameter Comparison

Engineering Selection Recommendations

The CD74ACT541E serves as a direct functional equivalent to the CD74ACT541EG4. Both components share identical electrical specifications and physical packaging, enabling pin-for-pin substitution in circuit applications.

The primary distinction between these parts relates to product status and compliance certification. The CD74ACT541EG4 carries ROHS3 compliance and REACH unaffected status, while the CD74ACT541E is classified as RoHS non-compliant and obsolete. Selection between these alternatives should be based on system-level compliance requirements and regulatory constraints applicable to the end application.

Frequently Asked Questions (FAQ)

Q: Can the CD74ACT541E replace the CD74ACT541EG4 in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including logic function, output current, supply voltage, operating temperature range, and 20-DIP package configuration. Direct substitution is feasible from a functional standpoint.

Q: What is the difference between these two part numbers?

A: The primary differences are manufacturer origin (Texas Instruments versus Harris Corporation), product status (discontinued versus obsolete), and compliance certifications (ROHS3 compliant versus RoHS non-compliant). Electrical and mechanical specifications are identical.

Q: Are there packaging differences between these parts?

A: The CD74ACT541EG4 is supplied in standard packaging, while the CD74ACT541E is supplied in tube packaging. Both use the 20-PDIP package form factor with identical pin configuration and physical dimensions.

Q: What compliance considerations apply to substitution?

A: The CD74ACT541EG4 meets ROHS3 and REACH requirements. The CD74ACT541E does not meet RoHS compliance. Applications subject to RoHS regulations should verify compliance requirements before selecting the CD74ACT541E as a substitute.

Q: Are the pin configurations identical?

A: Yes. Both parts use the 20-DIP package with identical pinout, enabling direct board-level substitution without circuit modification.
