Parameter Comparison

Engineering Selection Recommendations

The CD74ACT05E is electrically and mechanically equivalent to the CD74ACT05EG4. Both parts share identical logic function, pin configuration, electrical performance, and package specifications.

Selection considerations:

• The CD74ACT05EG4 is ROHS3 compliant, while the CD74ACT05E is RoHS non-compliant. Applications subject to RoHS regulations should prioritize the CD74ACT05EG4 or seek alternative sources.
• Both parts are discontinued or obsolete. Inventory availability should be verified with component distributors.
• The CD74ACT05E is available in tube packaging, while the CD74ACT05EG4 packaging specification is not provided in the input data.

Frequently Asked Questions (FAQ)

Q: Can the CD74ACT05E directly replace the CD74ACT05EG4?

A: Yes. The CD74ACT05E is electrically and mechanically equivalent. Both parts have identical logic type, circuit count, input/output specifications, voltage supply range, quiescent current, output current ratings, input logic levels, propagation delay, operating temperature range, and 14-DIP package configuration.

Q: What are the key differences between these parts?

A: The primary differences are manufacturer (Texas Instruments vs. Harris Corporation), product status (discontinued vs. obsolete), and RoHS compliance status (ROHS3 compliant vs. RoHS non-compliant).

Q: Are there any compatibility concerns with the 14-DIP package?

A: No. Both parts use the same 14-DIP (0.300", 7.62mm) through-hole package with identical pin configuration, ensuring direct PCB compatibility.

Q: Which part should I select for new designs?

A: Selection depends on regulatory requirements and availability. For RoHS-regulated applications, the CD74ACT05EG4 is compliant. Verify current inventory status with authorized distributors before finalizing component selection.

Q: Are the electrical characteristics identical?

A: Yes. Both parts have identical voltage supply range (4.5V ~ 5.5V), quiescent current (4 µA maximum), output current (24mA), input logic levels (0.8V low, 2V high), propagation delay (10.8ns @ 5V, 50pF), and operating temperature range (-55°C ~ 125°C).
