CD74HC11MT AND Gate IC 3 Channel 14-SOIC Equivalent & Substitute Parts

Part Overview

The CD74HC11MT is a 3-channel AND gate logic IC manufactured by Texas Instruments in 14-SOIC surface mount packaging. This part is discontinued at DiGi Electronics, making equivalent and substitute parts necessary for ongoing design support and procurement. The CD74HC11MT operates across a 2V to 6V supply voltage range and is suitable for general-purpose logic applications requiring multiple independent AND gate functions in a compact form factor.

Substitute Part Grouping Explanation

Substitution for the CD74HC11MT is determined by strict equivalence across the following critical parameters:

Logic Type: AND Gate with 3 circuits and 3 inputs per circuit
Voltage Supply Range: 2V ~ 6V
Package Type: 14-SOIC surface mount
Propagation Delay: 17ns maximum at 6V, 50pF load
Operating Temperature Range: -55°C ~ 125°C minimum
Output Current Capability: 5.2mA high and low
RoHS3 Compliance and MSL Level 1 rating

Substitute parts are grouped into two categories: parametric equivalents (identical electrical specifications) and manufacturer-recommended alternatives (functionally equivalent with minor specification variations acceptable for the 74HC11 logic family).

Engineering Selection Recommendations

For active production designs requiring CD74HC11MT replacement, the following parts are recommended based on product status and compliance:

Primary Recommendation: 74HC11D,653 (NXP Semiconductors) is the preferred substitute. This part maintains full parametric equivalence with the CD74HC11MT, carries Active product status, and holds ROHS3 compliance with unlimited moisture sensitivity rating. It is available in bulk packaging with 45,823 units in stock.

Secondary Recommendation: MC74HC11ADR2G (onsemi) offers superior performance characteristics with lower quiescent current (1 µA vs. 2 µA) and faster propagation delay (16ns vs. 17ns). This part is Active, ROHS3 compliant, and available in Tape & Reel packaging with 30,523 units in stock. The extended temperature range (-55°C ~ 125°C) matches the original CD74HC11MT specification.

Automotive Grade Option: 74HC11D-Q100J (Nexperia USA Inc.) is suitable for automotive applications requiring AEC-Q100 qualification. This part is Active, ROHS3 compliant, and available in Tape & Reel packaging with 967 units in stock.

Obsolete Parts: CD74HC11M96, 74HC11D,652, and NLV74HC11ADR2G are obsolete or discontinued and should not be selected for new designs despite technical compatibility.

Frequently Asked Questions (FAQ)

Q: Can I use 74HC11D,653 as a direct replacement for CD74HC11MT?

A: Yes. Both parts share identical logic function (3-channel AND gate), package type (14-SOIC), voltage supply range (2V ~ 6V), output current capability (5.2mA), and propagation delay (17ns at 6V, 50pF). The 74HC11D,653 is Active and ROHS3 compliant, making it suitable for direct substitution.

Q: What is the difference between MC74HC11ADR2G and 74HC11D,653?

A: Both are functionally equivalent AND gate ICs in 14-SOIC packaging. The MC74HC11ADR2G offers lower quiescent current (1 µA vs. 2 µA) and faster propagation delay (16ns vs. 17ns). The MC74HC11ADR2G is supplied in Tape & Reel packaging, while 74HC11D,653 is supplied in bulk. Both are Active and ROHS3 compliant.

Q: Is the CD74HC11M96 a suitable substitute?

A: CD74HC11M96 is parametrically equivalent but is marked as Obsolete and is not RoHS3 compliant. It should not be used for new designs. Use 74HC11D,653 or MC74HC11ADR2G instead.

Q: What packaging options are available for substitutes?

A: Substitute parts are available in multiple packaging formats: Tape & Reel (TR), Bulk, Tube, and Cut Tape (CT) & Digi-Reel. All maintain the same 14-SOIC surface mount package type. Select packaging based on procurement volume and assembly requirements.

Q: Can I use NLV74HC11ADR2G as a replacement?

A: NLV74HC11ADR2G is marked as Obsolete and should not be selected for new designs. Although it is ROHS3 compliant and AEC-Q100 qualified, its 25ns propagation delay exceeds the 17ns specification of the CD74HC11MT. Use MC74HC11ADR2G or 74HC11D,653 instead.

Q: Are all substitute parts RoHS3 compliant?

A: All recommended active substitutes (74HC11D,653, MC74HC11ADG, MC74HC11ADR2G, and 74HC11D-Q100J) are ROHS3 compliant. CD74HC11M96 is not RoHS3 compliant and should not be used for new designs.
