CD74HCT11E Equivalent & Substitute Parts

Part Overview

The CD74HCT11E is a 3-channel AND gate logic IC manufactured by Texas Instruments, housed in a 14-pin DIP package. This component is actively produced and widely used in digital logic applications requiring multiple independent AND gate functions. The device operates within the 4.5V to 5.5V supply voltage range and is RoHS3 compliant. Finding equivalent or substitute parts may be necessary due to inventory constraints, regional availability, or design flexibility requirements while maintaining functional compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the CD74HCT11E is determined by the following critical parameters:

• Logic function classification (AND gate with 3 channels, 3 inputs per channel)
• Supply voltage range (4.5V ~ 5.5V)
• Package type and pin configuration (14-DIP through-hole)
• Electrical characteristics (propagation delay, output current, input logic levels)
• Product status and compliance certifications (Active status, RoHS3 compliance)

The identified substitute part, 74HCT4040D,652 from NXP Semiconductors, is listed in the manufacturer's substitute database. However, this part functions as a binary counter element rather than an AND gate, indicating a functional difference from the main part. Substitution decisions must account for the actual logic function required in the application circuit.

Parameter Comparison

Engineering Selection Recommendations

Both parts maintain Active product status and REACH Unaffected compliance, indicating ongoing manufacturer support and regulatory alignment. The CD74HCT11E remains the primary selection for applications requiring AND gate logic functions. The 74HCT4040D,652 substitute is listed in the manufacturer database but serves a different functional purpose as a binary counter element. Selection between these parts must be based on the specific logic function required in the circuit design. Both parts comply with RoHS3 requirements and operate within the 74HCT logic family standards.

Frequently Asked Questions (FAQ)

Q: Can the 74HCT4040D,652 directly replace the CD74HCT11E in all applications?

A: No. The 74HCT4040D,652 is a binary counter element, while the CD74HCT11E is a 3-channel AND gate. Direct substitution is only valid if the application circuit requires counter functionality rather than AND gate logic.

Q: What are the key compatibility criteria for AND gate substitutes?

A: Compatible substitutes must maintain the same logic function (AND gate), number of channels (3), inputs per channel (3), supply voltage range (4.5V ~ 5.5V), and package type (14-DIP through-hole).

Q: Are there packaging differences between these parts?

A: Yes. The CD74HCT11E is supplied in Tube packaging, while the 74HCT4040D,652 is supplied in Bulk packaging. This affects handling, storage, and ordering considerations but does not impact electrical functionality.

Q: Do both parts meet current compliance standards?

A: Yes. Both parts are RoHS3 compliant and REACH Unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

Q: What is the moisture sensitivity difference between these parts?

A: The CD74HCT11E has Not Applicable MSL rating, while the 74HCT4040D,652 has MSL 1 (Unlimited). This affects storage and handling protocols, with MSL 1 allowing unlimited shelf life under standard conditions.
