CD74HC11M Equivalent & Substitute Parts

Part Overview

The CD74HC11M is a 3-channel AND gate logic integrated circuit manufactured by Texas Instruments in a 14-SOIC surface mount package. This part is classified as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing design support and procurement. The CD74HC11M operates across a 2V to 6V supply voltage range and is suitable for general-purpose digital logic applications requiring AND gate functionality with three independent channels, each accepting three inputs.

Substitute Part Grouping Explanation

Substitution of the CD74HC11M is determined by strict equivalence across the following critical parameters: logic type (AND gate), number of circuits (3), number of inputs per circuit (3), supply voltage range (2V ~ 6V), package type (14-SOIC), and mounting type (surface mount). All substitute parts must maintain identical functional specifications for these core parameters to ensure direct replacement capability.

The substitute parts are grouped into two categories based on product status and compliance:

Active Status Parts: MC74HC11ADR2G, MC74HC11ADG, and 74HC11D,653 are currently in active production and carry ROHS3 compliance certification, making them preferred for new designs and long-term availability.

Obsolete Status Parts: CD74HC11M96, 74HC11D,652, and NLV74HC11ADR2G are classified as obsolete but remain functionally equivalent and available in inventory. These parts are suitable for legacy system maintenance and repair applications.

Engineering Selection Recommendations

For Active Production Designs:

The MC74HC11ADR2G (onsemi, Tape & Reel packaging) is the primary recommended substitute. This part is in active production status, carries ROHS3 compliance certification, and offers improved quiescent current performance (1 µA versus 2 µA) with equivalent propagation delay characteristics (16ns). The Tape & Reel packaging format supports high-volume manufacturing processes.

The 74HC11D,653 (NXP Semiconductors, Bulk packaging) is an alternative active-status substitute with ROHS3 compliance. This part maintains full functional equivalence with the CD74HC11M and is available in high inventory quantities (45,823 pieces).

For Automotive Applications:

The 74HC11D-Q100J (Nexperia USA Inc.) is designated for automotive-grade applications with AEC-Q100 qualification. This part is in active production and carries ROHS3 compliance, making it suitable for automotive system designs requiring qualified components.

The NLV74HC11ADR2G (onsemi) provides automotive-grade qualification with AEC-Q100 certification, though it is classified as obsolete. This part is suitable for legacy automotive system maintenance.

For Legacy System Maintenance:

The CD74HC11M96 (Harris Corporation) maintains functional equivalence but is not RoHS compliant and is classified as obsolete. This part is suitable only for direct replacement in existing systems where RoHS compliance is not required.

The 74HC11D,652 (Nexperia USA Inc.) is an obsolete substitute with ROHS3 compliance, available in Tube packaging format.

Frequently Asked Questions (FAQ)

Q: Can the MC74HC11ADR2G directly replace the CD74HC11M in existing designs?

A: Yes. The MC74HC11ADR2G maintains identical logic functionality, pin configuration, and electrical specifications across all critical parameters including supply voltage range (2V ~ 6V), input/output logic levels, and propagation delay characteristics. The primary difference is improved quiescent current performance (1 µA versus 2 µA) and active production status.

Q: What is the difference between 14-SOIC and 14-SO package designations?

A: Both designations refer to 14-pin small-outline integrated circuit packages with identical physical dimensions (0.154" width, 3.90mm). The designations are manufacturer-specific nomenclature variations. Parts in either package type are mechanically and electrically interchangeable on standard PCB layouts.

Q: Why is the CD74HC11M classified as obsolete?

A: Obsolete classification indicates the manufacturer has discontinued production. However, the part remains functionally valid and is available through existing inventory channels. Active-status substitutes such as MC74HC11ADR2G and 74HC11D,653 are recommended for new designs to ensure long-term supply availability.

Q: Are all substitute parts RoHS compliant?

A: No. The CD74HC11M96 is not RoHS compliant. All other substitutes listed (MC74HC11ADR2G, MC74HC11ADG, 74HC11D,652, 74HC11D,653, 74HC11D-Q100J, and NLV74HC11ADR2G) carry ROHS3 compliance certification. RoHS compliance is mandatory for applications subject to European Union regulations.

Q: What is the significance of AEC-Q100 qualification?

A: AEC-Q100 qualification indicates the part meets automotive industry reliability and quality standards established by the Automotive Electronics Council. Parts with this qualification (74HC11D-Q100J and NLV74HC11ADR2G) are suitable for automotive applications where component qualification is required.

Q: Does propagation delay variation affect substitution compatibility?

A: Propagation delay differences within the specified range do not prevent substitution. The CD74HC11M specifies 17ns maximum delay, while MC74HC11ADR2G and MC74HC11ADG specify 16ns, and NLV74HC11ADR2G specifies 25ns. All values remain within acceptable logic timing margins for standard digital applications. Applications with critical timing requirements must verify delay specifications against circuit design parameters.

Q: What packaging formats are available for the substitute parts?

A: Substitute parts are available in four packaging formats: Tube (MC74HC11ADG, 74HC11D,652), Bulk (CD74HC11M96, 74HC11D,653), Tape & Reel (MC74HC11ADR2G, 74HC11D-Q100J), and Cut Tape & Digi-Reel (NLV74HC11ADR2G). Selection depends on manufacturing volume requirements and assembly process specifications.

Q: Is the CD74HC11M suitable for new product designs?

A: No. The CD74HC11M is classified as obsolete and should not be specified for new designs. Active-status alternatives such as MC74HC11ADR2G or 74HC11D,653 are recommended to ensure component availability throughout the product lifecycle.
